Earthquakes (E201)

Front

What is a tsunami?

Back

A giant ocean wave often caused by the sudden movement of oceanic tectonic plates (earthquakes).

Front

TRUE OR FALSE: Scientists figured out that Earth's Outer Core is liquid by studying how P-waves and S-waves (seismic Body waves) travel through the Earth.

Back

TRUE

Front

What type of Body wave is faster and can move through all layers of the Earth including solids, liquids, and gases?

Back

Primary wave (P-wave).

Front

At which type(s) of tectonic plate boundaries do earthquakes tend to happen?

Back

All three types of boundaries: TRANSFORM, CONVERGENT, and DIVERGENT.

Front

What is the focus (hypocenter) of an earthquake?

Back

The area deep underground where an earthquake originates.

Front

What is the epicenter of an earthquake?

Back

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

Front

What are seismic waves?

Back

Waves of energy that travel through the Earth, produced by earthquakes or other geological activity.

Front

What is the difference between P-waves and S-waves?

Back

P-waves (Primary waves) are faster and can travel through solids, liquids, and gases, while S-waves (Secondary waves) can only travel through solids.

Front

What is a fault line?

Back

A fracture or zone of fractures between two blocks of rock, which can cause earthquakes.

Front

What is the Richter scale?

Back

A scale used to measure the magnitude of an earthquake based on the amplitude of seismic waves.
