Front

What is the epicenter of an earthquake?

Back

The epicenter is the point on Earth's surface directly above the earthquake's focus.

Front

What are seismic waves?

Back

Seismic waves are waves of energy that travel through the Earth, generated by earthquakes.

Front

What is a fault line?

Back

A fault line is a crack in the Earth's surface where tectonic plates meet and can cause earthquakes.

Front

What is the focus of an earthquake?

Back

The focus is the point inside the Earth where an earthquake originates.

Front

What is a tsunami?

Back
