Front

What is an S wave?

Back

A type of seismic wave that can move through solid layers of the Earth but not through the liquid outer core.

Front

What is a P wave?

Back

A type of seismic wave that can move through both solid and liquid layers of the Earth.

Front

What are surface waves?

Back

Seismic waves that travel along the Earth's surface and are typically the most destructive.

Front

What is a seismograph?

Back

The point on the Earth's surface directly above where an earthquake originates.

Front

What is the focus of an earthquake?

Back

Front

What is compression stress?

Back

A type of stress that pushes rocks together, often causing reverse faults.

Front

What is tension stress?

Back

A type of stress that pulls rocks apart, often causing normal faults.

Front

What is shearing stress?

Back

A type of stress that causes rocks to slide past each other, often resulting in strike-slip faults.

Front

What factors contribute to building damage during an earthquake?

Back

The strength of building materials, proximity to the epicenter, soil type, and building design.
