Welcome to the latest article ‘fun facts about Volcano for kids‘.
I know that they are dangerous ,in only some time they can destroy cities,
But do you know they have created 80% of our planet’s surface, they found on every continent and also in Antarctica, many people live near Volcanoes and they can also be of different shapes.
Aren’t these facts interesting and fun? Do you know such fun facts about Volcano for kids if yes then read the whole article.
First let’s know what is Volcanoes, their types ,how they have formed.
- What is Volcano
A volcano is a kind of hole in the earth's crust that allows lava, volcanic ash, and gases to escape.
- What are types of volcano
Active volcano is a kind of volcano that has erupted in history and may erupt again.
There are around 1500 active volcanoes.
Dormant volcano is a kind of active volcano that hasn’t erupted recently but is expected to erupt again.
Extinct volcano is a volcano that hasn’t erupted in 10,000 years and also does not have chances to erupt again.
3. How they have formed
Volcanoes have formed when magma travels from the Earth’s mantle to its surface.
Pressure builds up inside the volcano that pushes magma, through cracks in it.
Fun facts about Volcano for kids
They are also known as Earth’s architects as their explosive force created mountains and also craters.
Do you know that volcanoes have created more than 80 percent of our planet’s surface and laid the foundation that has allowed life to thrive?
They have created remarkably fertile soils that have allowed civilizations to flourish.Gasses emissions from volcanoes formed the earth’s atmosphere.
Volcanic eruptions are too powerful and dangerous.
I think it is not important to tell how dangerous volcanic eruptions are because you already know, but let’s take a example-
The 1883 eruption of the volcano Krakatoa killed nearly 36,000 people.
It was one of the loudest sounds ever made and many scientists say it had the strength of many nuclear bombs.
And one of the biggest eruptions held had plunged the earth into a world wide ice age.
Biggest Volcano of the solar system
The object in our solar system that has the most volcanic activity is Io, one of Jupiter’s moons.
Some evidence from the Venus spacecraft suggests that many of Venus’s volcanoes are active.
Have you ever thrown rocks into the lake? Of course. Always when we throw it goes into water but is there any rock that can float on water?
Yes,There that is formed by magma it is called pumice.
It is also used as an abrasive and is sometimes also used in beauty salons for removing dry skin.
Mission mars in the Volcano
For several years, NASA has been simulating life on Mars on the slopes of a volcano, that is one of the Decade Volcanoes.
Each year, a small team of adventurers who have the basic qualifications for the NASA astronaut program goes there.
During this if they want to go outside, they have to put on space suits. Still it is decade Volcano, but still there are some poisonous gases and pyroclastic flows.
People near Volcano
Many people live near a Volcano .
People choose to live near volcanoes because it’s fertile soil, there is geothermal energy and minerals and they are good for tourism also.
With time, lava and ash break down to produce nutrient-rich soil, great for growing crops!
That’s why some people set up their homes on the slopes of a volcano.
Around 500 million people live close to volcanoes!
Most of them know very less about volcanoes
More people need to learn about it, like you are doing.
Some volcanoes can form overnight.
As we know some volcanoes can take thousands of years to form,
But do you know that there are also some volcanoes that can grow overnight.
For example, the cinder cone – Volcano Paricutin. That appeared in a Mexican cornfield on February 20, 1943.
In only a week it was 5 stories tall, and by the end of the year it was around 336 meters tall.
It ended its growth in 1952, with a height of 424 meters. According to geology, that’s pretty quick.
Magma and lava are two different things!
Magma is the hot liquid inside Volcano. Once it goes out of the volcano, it’s known as lava.
Temperature of lava from a volcano can even reach upto 1,250°C!
Lava is so hot it can burn everything that comes in its path. If you used a glass thermometer to take the temperature of it, then it would melt!
Do you know the tallest and biggest have little difference between them?
The tallest volcano on Earth’s surface is Hawaii’s Mauna Kea, with 4,207 meters elevation.
It’s only a few metres bigger than the largest volcano on Earth, Mauna Loa which has an elevation of 4,169 meters.
Both volcanoes have risen from the bottom of the ocean.
If we measure Mauna Kea from the base of the ocean to its peak, we’d get a height of 10,203 meters (and that’s bigger than Mount Everest).
Ring of fire is a ring of mountains
Most of the Volcanoes were found where tectonic plates meet. This is 100% true for the Pacific Ring of Fire, an area around the Pacific Ocean where 75% of Earth’s volcanoes are found.
Which is the oldest volcano?
The oldest volcano is Etna and it is around 350,000 years old.
Most of the active volcanoes about which we know seems to be less than 100,000 years old.
Shark near a Volcano
In 2015, scientists recorded a video of a shark happily swimming around in the acidic, hot, ash- and gas-filled waters near the underwater volcano in the Solomon Islands, which is nearly 66 feet below the surface.
This tells us that sharks are tough.
Most no of Volcanoes
Indonesia has the most Volcanoes. It is really a special place because from there you will see volcanoes all around, in all directions.
Merapi that is in Indonesia ( means “mountain of fire”) had erupted in January 1994 and in that few hundred people died.
Some islands such as Hawaii and Iceland are also known volcanic islands and they have black beaches.
The sand of these islands is made up of the hot lava, when this lava get cool, and creates an igneous rock called basalt.
Do you know that there are also volcanoes found on the ocean floor and even under icecaps?
On Earth’s surface there are at least 1,500 active volcanoes.
According to an estimate, the ocean contains 10,000 volcanoes!
We just don’t have many chances to see them because they are hidden away!
Eruption in Italy.
In A.D. 79, the Italian town named Pompeii was destroyed and buried by an volcanic eruption.
Incredibly, the ash deposits preserved the town. Today, it’s one of the most popular historical sites in Italy.
One of the biggest eruptions ever occurred on Earth is volcanic eruptions that occurred nearly 30 million years ago in what is today eastern Nevada and western Utah.
It occurred when a supervolcano threw 3500 cubic kilometers of magma over an area of about 12,000 square miles.
Some more interesting things about Volcano
Volcanoes also can be said as giant safety valves that release the pressure that builds up inside the Earth.
Huge slabs called Plates make Earth’s crust, which fit together like a jigsaw puzzle. These plates sometimes move.
When two plates collide with each other, one section slides on top of the other, the one beneath is pushed down. Magma is squeezed out and volcano forms.
Common gases that are released during volcanic eruption are- water vapor, carbon dioxide, sulfur dioxide, hydrogen chloride, hydrogen fluoride and hydrogen sulfide.
Dangerous area around a volcano covers about a 20 miles radius.
Volcanic eruptions can send ash high into the sky, over 30km (17 miles) above the Earth’s surface.
Volcanoes can be a variety of shapes.
When we imagine a Volcano, we mostly imagine a cone shaped mountain but volcano found also in other shapes
Volcanoes come in various shapes and sizes, like – cone shaped, cylindrical, shield and composite cones.
These can be dangerous in many ways.
Volcanic ash, made of pulverized rock, can be very harsh, acidic, gritty, glassy and smelly.
This ash can cause damage to the lungs of older people, babies and people who have respiratory problems.

Volcanoes are also known as nature’s architects, they may have different shapes and many people love to live near a Volcano.
