Question 1

What is a volcano?

Accepted Answer

A volcano is like a big mountain that can erupt, shooting out lava, ash, and gas from inside the Earth. It's kind of like a big, fiery zit on the Earth's skin.

Question 2

How do volcanoes form?

Accepted Answer

Volcanoes form when hot, melted rock from deep inside the Earth called magma pushes its way to the surface. Over time, this can create a mountain, which is a volcano.

Question 3

What causes a volcano to erupt?

Accepted Answer

A volcano erupts when there is a lot of pressure from gases and magma inside the Earth that needs to get out. It's like shaking a soda bottle and then opening it—everything comes rushing out!

Question 4

What is lava?

Accepted Answer

Lava is the name for hot, melted rock after it comes out of a volcano. Before it reaches the surface, it's called magma.

Question 5

Why do some volcanoes stay quiet for a long time?

Accepted Answer

Volcanoes can stay quiet because the magma chamber under them isn't ready to explode yet. It might take hundreds or even thousands of years before a volcano erupts again.

Question 6

What happens during a volcanic eruption?

Accepted Answer

During a volcanic eruption, hot lava, ash, and gases burst out of the volcano. This can make loud noises and cause lots of changes to the land around it.

Question 7

Can volcanoes create new land?

Accepted Answer

Yes, when lava cools and hardens, it can create new land. Islands like Hawaii were made by volcanoes over many years.

Question 8

What is a crater?

Accepted Answer

A crater is a big, bowl-shaped hole at the top of a volcano. It's where the lava, ash, and gases come out during an eruption.

Question 9

What are some different types of volcanoes?

Accepted Answer

There are different types of volcanoes, like shield, cinder cone, and stratovolcanoes. They look different depending on how they erupt and what they're made of.

Question 10

Are volcanoes dangerous?

Accepted Answer

Volcanoes can be dangerous because eruptions can destroy homes, plants, and animals. But scientists work hard to predict eruptions to keep people safe.

Question 11

What is ash from a volcano?

Accepted Answer

Volcanic ash is tiny bits of rock and glass that come out when a volcano erupts. It's so fine it can travel far and make it hard to breathe.

Question 12

Can you see a volcano erupting safely?

Accepted Answer

You can watch a volcano erupt from a safe distance or on TV. People shouldn't get too close because eruptions are unpredictable and dangerous.

Question 13

What are dormant and active volcanoes?

Accepted Answer

An active volcano erupts often, while a dormant one hasn't erupted in a long time but could do so again. Dormant means it's resting, but not asleep forever.

Question 14

Can volcanoes erupt in the ocean?

Accepted Answer

Yes, volcanoes can erupt in the ocean and create new islands. These underwater eruptions are usually less dangerous because they are far from people.

Question 15

Why do we study volcanoes?

Accepted Answer

We study volcanoes to understand how they work and to help keep people safe. Learning about volcanoes also helps us learn more about the Earth.

Question 16

What happens to plants and animals when a volcano erupts?

Accepted Answer

Eruptions can cover plants and animals with lava or ash, which can be harmful. But over time, new plants grow and animals come back to the area.

Question 17

Do all volcanoes look the same?

Accepted Answer

No, volcanoes can look different based on how they erupt and what they're made of. Some are wide with gentle slopes, while others are tall and steep.

Question 18

How do scientists know when a volcano might erupt?

Accepted Answer

Scientists watch for signs like small earthquakes, gas emissions, and changes in the volcano's shape. These signs can help them predict an eruption.

Question 19

What is a volcanic cone?

Accepted Answer

A volcanic cone is the mound of lava and ash that builds up around a volcano's opening. It gives the volcano its shape, kind of like an upside-down ice cream cone.

Question 20

Can extinct volcanoes erupt again?

Accepted Answer

No, extinct volcanoes won't erupt again. They're considered extinct because they haven't erupted for a very long time and aren't expected to in the future.
