Earthquakes

Front

What is the lithosphere?

Back

The lithosphere is the stiff, rigid outer layer of the Earth that includes the crust and upper mantle.

Front

What are Love waves?

Back

Love waves are a type of surface seismic wave that are the most damaging during an earthquake.

Front

What is the epicenter of an earthquake?

Back

The epicenter is the point on the Earth's surface directly above the origin (focus) of the earthquake.

Front

What are the two types of surface waves?

Back

The two types of surface waves are Love waves and Rayleigh waves.

Front

What are Primary waves?

Back

Primary waves (P waves) are the fastest kind of seismic waves and can travel through solids, liquids, and gases.

Front

What is the focus of an earthquake?

Back

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

Front

What are Rayleigh waves?

Back

Rayleigh waves are a type of surface seismic wave that cause both vertical and horizontal ground movement.

Front

What is the difference between body waves and surface waves?

Back

Body waves travel through the Earth's interior (P waves and S waves), while surface waves travel along the Earth's surface.

Front

What are Secondary waves?

Back

Secondary waves (S waves) are seismic waves that are slower than P waves and can only travel through solids.

Front

What is seismic activity?

Back

Seismic activity refers to the frequency and intensity of earthquakes in a given area.
