Question 1

What is an earthquake?

Accepted Answer

An earthquake is when the ground shakes suddenly. This happens because rocks underground break and move.

Question 2

What causes an earthquake?

Accepted Answer

Earthquakes happen because the Earth's plates, which are big pieces of land under the surface, bump into each other or slide past one another.

Question 3

Can earthquakes happen anywhere?

Accepted Answer

Earthquakes can happen anywhere, but they are most common near the edges of the Earth's plates, where they move the most.

Question 4

How do scientists measure earthquakes?

Accepted Answer

Scientists use a tool called a seismograph to measure how big and strong an earthquake is. This tool records the shaking of the ground.

Question 5

What is a fault line?

Accepted Answer

A fault line is a crack in the Earth's surface where earthquakes often happen. It's where two pieces of the Earth's crust meet.

Question 6

Why do we sometimes feel aftershocks?

Accepted Answer

Aftershocks are smaller shakes that happen after the main earthquake. They happen because the rocks are settling into their new positions.

Question 7

What should I do if there's an earthquake?

Accepted Answer

If there's an earthquake, you should drop to the ground, cover your head, and hold on until the shaking stops. Stay away from windows and things that could fall.

Question 8

Can animals sense earthquakes before they happen?

Accepted Answer

Some people believe animals can feel earthquakes before we can, but scientists aren't sure why this might happen. Animals might sense tiny shakes that we can't feel.

Question 9

Why do some places have more earthquakes than others?

Accepted Answer

Some places have more earthquakes because they are near the edges of the Earth's plates. These plates move and cause the ground to shake.

Question 10

What is the biggest earthquake ever recorded?

Accepted Answer

The biggest earthquake ever recorded was in Chile in 1960. It was so powerful it shook the whole planet.

Question 11

How long do earthquakes usually last?

Accepted Answer

Most earthquakes last less than a minute, but they can feel much longer when they're happening.

Question 12

Can scientists predict earthquakes?

Accepted Answer

Scientists can't predict exactly when an earthquake will happen, but they can study areas that are likely to have earthquakes and be prepared.

Question 13

What is a tsunami?

Accepted Answer

A tsunami is a huge wave that is usually caused by an undersea earthquake. The wave can be very dangerous when it reaches land.

Question 14

What are tectonic plates?

Accepted Answer

Tectonic plates are large pieces of the Earth's surface that move very slowly. Their movements can cause earthquakes.

Question 15

How do earthquakes affect buildings and roads?

Accepted Answer

Earthquakes can cause buildings and roads to crack or fall down. Engineers work to design buildings that can withstand shaking better.

Question 16

What is the Ring of Fire?

Accepted Answer

The Ring of Fire is an area around the edges of the Pacific Ocean where there are many earthquakes and volcanoes. It's shaped like a horseshoe.

Question 17

Why do buildings sometimes shake more during an earthquake?

Accepted Answer

Buildings can shake more if they are built on soft ground or if they're not designed to handle the shaking of an earthquake.

Question 18

What is magnitude?

Accepted Answer

Magnitude is a number that tells us how strong an earthquake is. The higher the number, the stronger the earthquake.

Question 19

How can I prepare for an earthquake?

Accepted Answer

You can prepare for an earthquake by having an emergency kit with things you might need, like water, food, and a flashlight. Know safe places in your house to take cover.

Question 20

What is liquefaction?

Accepted Answer

Liquefaction is when the ground acts like liquid during an earthquake. This can happen if the soil is very wet.
