Front

What is the definition of an earthquake epicenter?

Back

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

Front

What are P-waves?

Secondary waves that arrive after P-waves and can only travel through solids.

Front

What is the difference between a normal fault and a reverse fault?

Back

A normal fault occurs when the hanging wall moves down relative to the footwall, while a reverse fault occurs when the hanging wall moves up.

Front

What is the role of compaction in sedimentary rock formation?

Back

Compaction reduces the volume of sediment as particles are pressed together.
