Key Points To Remember When Writing An Essay On The Volcano For Lower Primary Classes

10 lines on the volcano for kids, a paragraph on the volcano for children, short essay on volcano in 200 words for kids, long essay on volcano for children, interesting facts about volcanoes for children, what will your child learn from this essay.

A volcano is a mountain formed through an opening on the Earth’s surface and pushes out lava and rock fragments through that. It is a conical mass that grows large and is found in different sizes. Volcanoes in Hawaiian islands are more than 4000 meters above sea level, and sometimes the total height of a volcano may exceed 9000 meters, depending on the region it is found. Here you will know and learn how to write an essay on a volcano for classes 1, 2 & 3 kids. We will cover writing tips for your essay on a volcano in English and some fun facts about volcanoes in general.

Volcanoes are formed as a result of natural phenomena on the Earth’s surface. There are several types of volcanoes, and each may emit multiple gases. Below are some key points to remember when writing an essay on a volcano:

  • Start with an introduction about how volcanoes are formed. How they impact the Earth, what they produce, and things to watch out for.
  • Discuss the different types of volcanoes and talk about the differences between them.
  • Cover the consequences when volcanoes erupt and the extent of the damage on Earth.
  • Write a conclusion paragraph for your essay and summarise it. 

When writing a few lines on a volcano, it’s crucial to state interesting facts that children will remember. Below are 10 lines on volcanoes for an essay for classes 1 & 2 kids.

  • Some volcanoes erupt in explosions, and then some release magma quietly.
  • Lava is hot and molten red in colour and cools down to become black in colour. 
  • Hot gases trapped inside the Earth are released when a volcano erupts.
  • A circle of volcanoes is referred to as the ‘Ring of Fire.’
  • Volcano formations are known as seismic activities.
  • Active volcanoes are spread all across the earth. 
  • Volcanoes can remain inactive for thousands of years and suddenly erupt.
  • Most volcanic eruptions occur underwater and result from plates diverging from the margins.
  • Volcanic hazards happen in the form of ashes, lava flows, ballistics, etc.
  • Volcanic regions have turned into tourist attractions such as the ones in Hawaii.

Volcanoes can be spotted at the meeting points of tectonic plates. Like this, there are tons of interesting facts your kids can learn about volcanoes. Here is a short paragraph on a volcano for children:

A volcano can be defined as an opening in a planet through which lava, gases, and molten rock come out. Earthquake activity around a volcano can give plenty of insight into when it will erupt. The liquid inside a volcano is called magma (lava), which can harden. The Roman word for the volcano is ‘vulcan,’ which means God of Fire. Earth is not the only planet in the solar system with volcanoes; there is one on Mars called the Olympus Mons. There are mainly three types of volcanoes: active, dormant, and extinct. Some eruptions are explosive, and some happen as slow-flowing lava.

Small changes occur in volcanoes, determining if the magma is rising or not flowing enough. One of the common ways to forecast eruptions is by analysing the summit and slopes of these formations. Below is a short essay for classes 1, 2, & 3:

As a student, I have always been curious about volcanoes, and I recently studied a lot about them. Do you know? Krakatoa is a volcano that made an enormous sound when it exploded. Maleo birds seek refuge in the soil found near volcanoes, and they also bury their eggs in these lands as it keeps the eggs warm. Lava salt is a popular condiment used for cooking and extracted from volcanic rocks. And it is famous for its health benefits and is considered superior to other forms of rock or sea salts. Changes in natural gas composition in volcanoes can predict how explosive an eruption can be. A volcano is labelled active if it constantly generates seismic activity and releases magma, and it is considered dormant if it has not exploded for a long time. Gas bubbles can form inside volcanoes and blow up to 1000 times their original size!

Volcanic eruptions can happen through small cracks on the Earth’s surface, fissures, and new landforms. Poisonous gases and debris get mixed with the lava released during these explosions. Here is a long essay for class 3 kids on volcanoes:

Lava can come in different forms, and this is what makes volcanoes unique. Volcanic eruptions can be dangerous and may lead to loss of life, damaging the environment. Lava ejected from a volcano can be fluid, viscous, and may take up different shapes. 

When pressure builds up below the Earth’s crust due to natural gases accumulating, that’s when a volcanic explosion happens. Lava and rocks are shot out from the surface to make room on the seafloor. Volcanic eruptions can lead to landslides, ash formations, and lava flows, called natural disasters. Active volcanoes frequently erupt, while the dormant ones are unpredictable. Thousands of years can pass until dormant volcanoes erupt, making their eruption unpredictable. Extinct volcanoes are those that have never erupted in history.

The Earth is not the only planet in the solar system with volcanoes. Many volcanoes exist on several other planets, such as Mars, Venus, etc. Venus is the one planet with the most volcanoes in our solar system. Extremely high temperatures and pressure cause rocks in the volcano to melt and become liquid. This is referred to as magma, and when magma reaches the Earth’s surface, it gets called lava. On Earth, seafloors and common mountains were born from volcanic eruptions in the past.

What Is A Volcano And How Is It Formed?

A volcano is an opening on the Earth’s crust from where molten lava, rocks, and natural gases come out. It is formed when tectonic plates shift or when the ocean plate sinks. Volcano shapes are formed when molten rock, ash, and lava are released from the Earth’s surface and solidify.

Types Of Volcanoes

Given below various types of volcanoes –

1. Shield Volcano

It has gentle sliding slopes and ejects basaltic lava. These are created by the low-viscosity lava eruption that can reach a great distance from a vent.

2. Composite Volcano (Strato)

A composite volcano can stand thousands of meters tall and feature mudflow and pyroclastic deposits.

3. Caldera Volcano

When a volcano explodes and collapses, a large depression is formed, which is called the Caldera.

4. Cinder Cone Volcano

It’s a steep conical hill formed from hardened lava, tephra, and ash deposits.

Causes Of Volcano Eruptions

Following are the most common causes of volcano eruptions:

1. Shifting Of Tectonic Plates

When tectonic plates slide below one another, water is trapped, and pressure builds up by squeezing the plates. This produces enough heat, and gases rise in the chambers, leading to an explosion from underwater to the surface.

2. Environmental Conditions

Sometimes drastic changes in natural environments can lead to volcanoes becoming active again.

3. Natural Phenomena

We all understand that the Earth’s mantle is very hot. So, the rock present in it melts due to high temperature. This thin lava travels to the crust as it can float easily. As the area’s density is compromised, the magma gets to the surface and explodes.

How Does Volcano Affect Human Life?

Active volcanoes threaten human life since they often erupt and affect the environment. It forces people to migrate far away as the amount of heat and poisonous gases it emits cannot be tolerated by humans.

Here are some interesting facts:

  • The lava is extremely hot!
  • The liquid inside a volcano is known as magma. The liquid outside is called it is lava.
  • The largest volcano in the solar system is found on Mars.
  • Mauna Loa in Hawaii is the largest volcano on Earth.
  • Volcanoes are found where tectonic plates meet and move.

Your child will learn a lot about how Earth works and why volcanoes are classified as natural disasters, what are their types and how they are formed.

Now that you know enough about volcanoes, you can start writing the essay. For more information on volcanoes, be sure to read and explore more.

Essay on Volcanoes

Essay Contents:

  • Essay on Volcanic Hazards

Essay # 1. Definition of Volcanoes:

A volcano is a vent or chimney which transfers molten rock known as magma from a depth to the Earth’s surface. Magma erupting from a volcano is called lava and is the material which builds up the cone surrounding the vent.

A volcano is active if it is erupting lava, releasing gas or generates seismic activity. A volcano is dormant if it has not erupted for a long time but could erupt again in the future. Once a volcano has been dormant for more than 10 000 years, it is termed extinct.

The explosiveness of a volcanic eruption depends on how easily magma can flow and the amount of gas trapped within the magma is released. Large amounts of water and carbon dioxide are dissolved in magma causing it to behave in a similar way as gas expanding in fizzy drinks, which forms bubbles and escapes after opening. As magma rises quickly through the Earth’s crust, gas bubbles are formed and expand up to 1000 times their original size.

Essay # 2. Occurrence of Volcanoes:

Active volcanoes generally occur close to the major tectonic plate boundaries.

Many are located along the Earth’s plate boundaries. Active volcanoes are rare in Australia because there are no plate boundaries on this continent. However, there are two active volcanoes located 4,000 kilometres south-west of Perth on the Australian territories, Heard Island and the nearby McDonald Islands.

The other active volcanoes near Australia are in New Zealand, Papua New Guinea, Indonesia and the Philippines. Gas-rich sticky magmas dominate the Asia Pacific, making composite volcanoes and calderas the most common varieties in the region. These types of volcanoes severely threaten lives, property, agricultural lands and lifelines throughout south-east Asia and the Australian region.

Volcanoes can remain inactive or dormant, for hundreds of thousands of years before erupting again. During this time they can remain covered by vegetation making them difficult to identify. Once a volcano has been dor­mant for more than 10,000 years, it is termed extinct.

Evidence for volcanism throughout geological time can be found in every Australian State and Territory, with extensive volcanism down the east coast during the past 60 million years. This volcanic activity can be divided into areas where large amounts of lava flowed from dif­fuse dykes and pipes over a wide area and others where volcanism was produced from either a single central vent or a cluster of vents.

It is thought that the central volcanoes were produced as the Australian continent moved over a hot spot in the underlying mantle which melted through the plate to form the volcano. As the continent moved northward, the stationary hot spot formed volcanoes further to the south of the continent. As a result, the rocks of central volcanoes down the east coast become younger as one move southward.

Essay # 3 . Causes of Volcano:

Volcanic activity frequently occurs at the bounda­ries of the Earth’s tectonic plates which are a series of large blocks moving between each other. The move­ment of these plates plays a significant role in the type of volcano formed which influences its shape.

i. Spreading Plate Margins :

Where plates move away from each other at spread­ing or divergent plate margins, volcanic eruptions are gentle extrusions of basaltic lava. Most of these occur underwater where magma rises from great depth below to fill the space created by seafloor spreading of which occurs at a rate of about 10 centimetres a year.

ii. Subducting Plate Margins :

At subducting plate margins, one plate is pushed under a neighbouring plate as they squeeze together. In addition to the old, weathered plate being forced down and melted wet sediment and seawater is forced down creating andesitic lava and more violent eruptions containing ash. These volcanoes form classic cone shapes.

Some volcanoes are found at great distances from plate boundaries and are referred to as intra- plate, within plate or hot spot volcanoes. These are formed above hot mantle upwellings or plumes which rise from great depths. As the plate overlying the plume moves away from the hot spot and a new volcano is formed, the previous one cools to become dormant and eventually extinct.

This sequence forms a volcanic chain such as the one currently found in the Hawaiian Islands. Hotspot volcanism forms very large, low gradient shield volcanoes and are similar in composition and eruption style to those found at divergent plate boundaries.

iii. Predicting Eruptions :

Understanding how volcanoes work and how their eruptions can be predicted is essential for the well-being and preservation of people who inhabit volcanically vulnerable areas. Eruptions can occur without any preceding signals, making them extremely difficult to predict. However, sometimes there are useful clues for judging when a volcano is likely to erupt.

A volcano’s eruptive history may provide some clues. However, because only a small number of the world’s volcanoes have a known history it is extremely difficult to predict future eruptions, particularly for certain types of volcanoes. This problem is typified by using the repose period, or the time between eruptions to indicate the expected size and strength of an eruption.

Consistently long repose periods may indicate that a volcano’s eruption is usually large and explosive. However, sometimes there is no clear relationship in the length of time between eruptions and the nature of the eruptions.

Essay # 5 . Volcanic Hazards:

Volcanic hazards include explosions, lava flows, bombs or ballistics, ash or tephra, pyroclastic flows, pyroclastic surges, mudflows or lahars, landslides, earthquakes, ground deformation, tsunami, air shocks, lightning, poisonous gas and glacial outburst flooding known as jӧkulhlaups. Each hazard has a different consequence, although not all occur in every eruption or in association with all the volcanoes.

Volcanic eruptions are measured using a simple descriptive index known as the Volcano Explosivity Index which ranges from zero to eight. The index com­bines the volume of material ejected with the height of an eruption column and the duration of the eruption.

Volcanoes Essays

Effects of Volcanoes The plates, which are about 20 miles thick, make up the Earth's crust and are a chief cause of volcanic activity. These plates are always in motion. They move very slowly; however, at times, they bump into each other. These movements put a lot of pressure on the surface rock. Volcanoes obtain their energy from such movement and pressure. Volcanoes form at the boundaries of these plates where two types of movement occur: two plates will collide with each other, or the plates will

Super Volcanoes Essay

Super Volcanoes There is no exact definition for a super volcano, but the expression is often used to refer to volcanoes that have produced extraordinarily large eruptions in the past. When one of these large eruptions occurs, a huge amount of material is blasted out of the super volcano, leaving a massive crater or caldera. A caldera can be as much as forty or fifty miles wide. At Yellowstone, the caldera is so big that it includes a fair amount of the entire park

An Article, a Short Story, and a Poem

article “Under the Volcano” is written by Jack McClintock and is the most informative. The persuasion to have people move away from the danger area of Mt. Rainier is very subtle. The article lists volcanoes that have erupted and when they did so. Throughout the article there are pictures of volcanoes and the corresponding text shows what is being done to monitor them. The focus of the piece is the danger to Seattle and Tacoma posed by Mt. Rainier. There is an illustration of the danger zones of

myself, was last summer when my boyfriend and I drove to Washington. It was the most beautiful, peaceful looking mountain I have ever seen. However, underneath it's great beauty, it hides a deadly secret. Mt. Rainier is one of the most dangerous volcanoes that we have here in the United States. One of the reasons it is so dangerous is because of it's great beauty. People enjoy looking at it, and the area that surrounds it, so they have made their homes here. Mt Rainier is not the only volcano I am

shifting causes two of Japan's most striking features-- earthquakes and volcanoes. The Japanese islands have about 1500 earthquakes a year. Most of them are minor tremors that cause little damage, but severe earthqaukes occur every few years. Underseaquakes sometimes cause huge, destructive tidal waves, called tsunami, along Japan's Pacific coast. The Japanese islands have more than 150 major volcanoes. Over 60 of these volcanoes are active. Numerous short, swift rivers cross Japan's rugged surface

Volcanoes Volcanoes are one of the most destructive yet fascinating geological land forms in our natural environment. They consist of a fissure in the earth's crust above which a cone of volcanic material has accumulated. The cone is formed by the deposition of molten or solid matter that flows from the interior of the earth through an indented vent, called a crater, which is found at the top of the cone. In this report I will discuss different states of volcanic activity, different

A Look Into Volcanoes I. Introduction Volcano: defined is a mountain or hill formed by the accumulation of materials erupted through one or more openings (called volcanic vents) in the earth's surface. The term volcano can also refer to the vents themselves. Most volcanoes have steep sides, but some can be gently sloping mountains or even flat tablelands, plateaus, or plains. The volcanoes above sea level are the best known, but the vast majority of the world's volcanoes lie beneath the

Volcanoes Volcanoes are natural phenomena which are on the Earth’s surface through which molten rock and gases escape from below the surface (Tarbuck, 139). These volcanoes are very interesting to observe and to study because of their amazing occurrences and majestic lava eruptions. Volcanoes have been studied ever since the beginning of mankind and the word “volcano” is thought to be derived from Vulcano, a volcanic island in the Aeolian Islands of Italy whose name in turn originates from Vulcan

Volcanoes Distribution Volcanoes can be described as being tectonic hazards that occur in many parts of the world. The distribution of volcanoes is closely linked with the positioning of the tectonic plate boundaries across the globe. Today there are about 500 active volcanoes in the world. The world map of volcanoes in your atlas shows that the most volcanic activity occurs along the West coasts of North and South America, (along the Rockies and Andes) and the coasts of many Far East countries

Volcanoes: An Essay: What Are Volcanoes?

What are volcanoes? A volcano is a mountain that opens downward to a pool of molten rock below the surface of the earth. When pressure builds up, eruptions occur. In another definition it is a mountain That has a passage to the underground molten seas of rocks , when the pressure increases on this molten seas it causes eruption gases and molten rocks shoot up through a hole in the top of the mountain and fill the air with lava fragments . This eruptions cause a leatral blasts ,lava flows , hot

The Three Stages Of Volcanoes, And Dormant Volcanoes

Volcanoes are magnificent and powerful land features. The magma erupts from the Earth forming islands, cooling to form rocks, and changing the landscape on eruption at a time. They can erupt at any time! Since volcanoes are dangerous we have developed technology to detect these impressive explosions. Since Hawaii was formed by a volcano when you visit Hawaii you are standing on cooled lava! There are 3 different stages a volcano can be in and 2 very different types of explosions that can happen.

I. Summary This paper will provide information on the volcanoes of Hawaii, where it is known to be the home of one of the world’s largest volcanic islands, merely second to Iceland. It is not just the beautiful landscapes and wildlife that spark the interest to this particular area, but the uniqueness of the Hawaiian volcanoes and islands themselves are what make the area so significant. There will be information spanning from the history of the origin of the islands to how Hawaii must adjust

The Danger Of Volcanoes: The Danger Of Volcanoes

Volcano. A word that we are all taught to simultaneously fear and question. An image that we admire through a screen, too afraid to look at up close. We think of its beauty and that fiery danger hidden within. The inevitable danger of a volcano is what most of us were taught and is what we believe, but do we really have to shy away from these explosive rocks? The answer is no. Many people live their everyday lives next to or near a volcano and tourists come from all around to see them. How do these

Volcanoes and Volcanology

Volcanoes can be one of the most destructive forces on Earth. It is estimated that some 500 million people live near active volcanoes (Lutgens and Tarbuck, 2013). Of the Earth's known volcanoes, 70 can be expected to erupt each year with at least one large eruption each decade (Lutgens & Tarbuck, 2013). As populations continue to increase and more people are attracted to the beauty surrounding these areas, the immediate threat to humans from these sometimes sleeping giants grows. Due to this

Volcanoes Essay

molten lava, and ash. Volcanoes are generally grouped into four categories: cinder cone, composite volcanoes, shield volcanoes, and lava domes. Cinder cone volcanoes are formed when gas-charged lava explodes into the air. The pieces of lava that fall from the air solidify and create a cone-shaped hill with a cup-shaped depression. Composite volcanoes are large, steep, symmetrical cones with a crater at the summit that contains a vent or cluster of vents. Composite volcanoes are responsible for some

Volcano Is The Most Active Volcano

The worst volcano known to man A volcano is defined as a mountain or hill that usually has a cup like crater at the summit. A volcano can be compared to a vent in the earths crust through which lava, ashes and steam are expelled (Volcano, n.d.). There are three main types of volcanoes that scientist have discovered active, dormant, and extinct (howstuffworks.com). Active volcanoes are the ones which have erupted recently, or are expected to blow soon (howstuffworks.com). For example Kilauea volcano

The Kilauea Volcano

Kilauea Volcano The Kilauea Volcano is the youngest and most active Hawaiian shield volcano. This volcano is located on Hawaii’s Big Island. The volcano is part of the Hawaii Volcanoes National Park. Kilauea is 300,000 to 600,000 years old. The native people from the Polynesian Islands discovered Kilauea. The other four volcanoes of Hawaii are Kohala, Mauna Loa, and Mauna Kea. “Shield volcanoes are the largest volcanoes on the earth” (“Volcano DIscovery”). This makes Kilauea a nice tourist attraction

This eruption caused major disruption in air travel and grounded thousands of flights in and around Europe. Iceland is an

Katmai Volcano

A volcano is a weak spot in the crust where molten material, or magma, comes to the surface. In a volcano there is a magma chamber, pipe, vent, lava flow, and craters. A magma chamber is the pocket where magma collects under or below a volcano. The pipe of a volcano is the long tube in the ground that connects the Earth's surface to the magma chamber. A vent in a volcano is where the molten rock and gas from the volcano leave through an opening. The lava flow is a certain area that is covered by
