Question 1

What is a volcano?

Accepted Answer

A volcano is a mountain that has a hole at the top that can let out lava, ash, and gases from deep inside the Earth.

Question 2

How are volcanoes formed?

Accepted Answer

Volcanoes are formed when magma, which is hot melted rock inside the Earth, pushes up through the Earth’s crust and makes a mountain.

Question 3

Why do volcanoes erupt?

Accepted Answer

Volcanoes erupt when the pressure inside the Earth builds up and forces magma to come out through the opening at the top.

Question 4

What is lava?

Accepted Answer

Lava is the hot, melted rock that comes out of a volcano during an eruption. When it cools down, it becomes hard rock.

Question 5

What are some different types of volcanoes?

Accepted Answer

There are three main types of volcanoes: cinder cone, shield, and composite. Each type has a different shape and eruption style.

Question 6

How can volcanoes change the landscape?

Accepted Answer

When a volcano erupts, the lava and ash can create new land, change the shape of mountains, and even form islands.

Question 7

Are volcanoes only found on land?

Accepted Answer

No, volcanoes can also be found underwater. There are more volcanoes under the sea than on land.

Question 8

What happens to plants and animals when a volcano erupts?

Accepted Answer

When a volcano erupts, it can be dangerous for plants and animals because the ash and lava can cover their homes.

Question 9

What is a volcanic island?

Accepted Answer

A volcanic island is an island that forms when lava from an underwater volcano builds up and rises above the water.

Question 10

Why are some volcanoes still active while others are not?

Accepted Answer

Some volcanoes are still active because they are closer to the places where the Earth's crust moves and lets magma through.

Question 11

What are the benefits of volcanoes?

Accepted Answer

Volcanoes make the soil very rich, which helps plants grow well. They also create beautiful landscapes and can form new land.

Question 12

Can people live near volcanoes?

Accepted Answer

Yes, some people choose to live near volcanoes because the soil is good for farming. However, they must be careful because eruptions can happen.

Question 13

What is ash from a volcano?

Accepted Answer

Volcanic ash is tiny pieces of rock and glass that volcanoes throw into the air during an eruption. It can cover large areas and affect breathing.

Question 14

How do scientists know when a volcano might erupt?

Accepted Answer

Scientists use special tools to watch for signs like earthquakes, gases, and changes in the shape of the volcano to predict eruptions.

Question 15

What is the largest volcano on Earth?

Accepted Answer

The largest volcano on Earth is Mauna Loa in Hawaii. It's so big because it has been erupting for hundreds of thousands of years.

Question 16

Can volcanic eruptions affect the climate?

Accepted Answer

Yes, volcanic eruptions can affect the climate because the ash and gases can block sunlight and cool the Earth for a while.

Question 17

What is a volcanic eruption's impact on people?

Accepted Answer

Volcanic eruptions can be dangerous for people nearby, destroying homes and forcing them to move to safer areas.

Question 18

Is it safe to visit a volcano?

Accepted Answer

Most of the time, it's safe to visit a volcano if it's not erupting. Many volcanoes are popular tourist spots because they are very interesting to see.

Question 19

What's the difference between magma and lava?

Accepted Answer

Magma is the hot, melted rock inside the Earth. When it comes out of a volcano, it is called lava.

Question 20

Why are some volcanoes tall while others are flat?

Accepted Answer

The shape of a volcano depends on how the lava flows. Fast-flowing lava can spread out and make flat volcanoes, while slow lava builds up tall ones.
