Front

What does the Richter scale measure?

Back

The Richter scale measures the strength of an earthquake.

Front

What is the difference between P Waves and S Waves?

Back

P Waves (Primary Waves) are compressional waves that can travel through solids and liquids, while S Waves (Secondary Waves) are shear waves that can only travel through solids.

Front

What is an anticline?

Back

An anticline is a type of fold that is arch-like in shape, where the oldest rock layers are found in the center.

Front

What is a syncline?

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

Front

What is the epicenter of an earthquake?

Back

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

Front

What are body waves?

Back

Body waves are seismic waves that travel through the Earth's interior, including P Waves and S Waves.

Front

What are surface waves?

Back

Surface waves are seismic waves that travel along the Earth's surface and typically cause the most damage during an earthquake.

Front

What is the difference between the hanging wall and the foot wall in a fault?

Back

The hanging wall is the block of rock that lies above the fault plane, while the foot wall is the block that lies below the fault plane.
