Front

What is the fastest seismic wave?

Back

The fastest seismic wave is the P wave.

Front

What is a 'push/pull' wave?

Back

A 'push/pull' wave refers to the P wave, which compresses and expands the material it travels through.

Front

Which seismic wave is the most destructive?

Back

The most destructive seismic wave is the S wave.

Front

How are metamorphic rocks formed?

Back

Metamorphic rocks are formed by the transformation of existing rocks under heat and pressure.

Front

What are seismic waves?

Back

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

Front

What is the difference between P waves and S waves?

Back

P waves are compressional waves that can travel through solids and liquids, while S waves are shear waves that can only travel through solids.

Front

What is the focus of an earthquake?

Back

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 is a tectonic plate?

Back

A tectonic plate is a large slab of solid rock that makes up the Earth's lithosphere and moves over the semi-fluid asthenosphere.
