Question 1

What causes a volcano to erupt?

Accepted Answer

Volcanoes erupt when hot, melted rock called magma rises to the surface. This happens because gases inside the magma build up pressure like shaking up a soda can until it pops!

Question 2

What is magma?

Accepted Answer

Magma is like super hot, melted rock inside the Earth. When it comes out of a volcano, we call it lava.

Question 3

Why is lava so hot?

Accepted Answer

Lava is hot because it comes from deep inside the Earth where it's very hot. It's hotter than the hottest oven!

Question 4

Are all volcanoes the same?

Accepted Answer

Not all volcanoes are the same. Some are like big mountains, while others are small or even underwater. They can also erupt differently.

Question 5

What happens when a volcano erupts?

Accepted Answer

When a volcano erupts, it spews out lava, ash, and gases. Sometimes it can be really explosive and send ash high into the sky!

Question 6

What is an ash cloud?

Accepted Answer

An ash cloud is made of tiny pieces of rock blasted into the air during an eruption. It looks like a giant gray cloud in the sky.

Question 7

Why do some volcanoes explode?

Accepted Answer

Some volcanoes explode because the magma has a lot of gas trapped inside, and when that gas escapes quickly, it causes a big boom!

Question 8

What are the dangers of a volcanic eruption?

Accepted Answer

Volcanic eruptions can be dangerous because they release lava, ash, and gases. These can destroy homes, create floods, and harm animals and people.

Question 9

Can we predict when a volcano will erupt?

Accepted Answer

Scientists use special tools to watch volcanoes for signs of eruptions, like small earthquakes. But, it's still very hard to know exactly when they will erupt.

Question 10

What is lava made of?

Accepted Answer

Lava is made of melted rocks and minerals. It's like a super hot, liquid stone that flows out of a volcano.

Question 11

Are volcanoes found everywhere on Earth?

Accepted Answer

Volcanoes are not everywhere. They mostly happen in places where the Earth's pieces, called tectonic plates, meet.

Question 12

Can volcanoes be underwater?

Accepted Answer

Yes, many volcanoes are underwater on the ocean floor. They can create new islands when they erupt!

Question 13

What is a dormant volcano?

Accepted Answer

A dormant volcano is one that has not erupted for a long time but might erupt again someday. It's like a sleeping volcano.

Question 14

What is an extinct volcano?

Accepted Answer

An extinct volcano is one that is not expected to erupt ever again. It's like an old volcano that has finished its active life.

Question 15

How does a volcanic eruption affect animals?

Accepted Answer

Volcanic eruptions can be harmful to animals by destroying their homes and making it hard to breathe because of the ash and gases.

Question 16

Can people live near volcanoes?

Accepted Answer

Yes, many people live near volcanoes. They do this because the land is often very fertile for farming due to the volcanic soil.

Question 17

What is a lava flow?

Accepted Answer

A lava flow is when lava comes out of a volcano and moves down its sides like a river of hot rock. It can burn and cover anything in its path.

Question 18

Why do some volcanoes have different shapes?

Accepted Answer

Volcanoes have different shapes based on how they erupt and the kinds of lava they produce. Some are tall and cone-shaped, while others are wide and flatter.

Question 19

What is a volcanic island?

Accepted Answer

A volcanic island is an island formed from the lava that builds up over time from many eruptions. Hawaii is a great example!

Question 20

What do scientists learn from studying volcanoes?

Accepted Answer

Scientists learn about how the Earth works by studying volcanoes. They also try to find ways to keep people safe from eruptions.
