Earthquakes (Pre)

Front

What are P Waves?

Back

P Waves, or Primary Waves, are seismic waves that are the first to be detected by seismographs. They can travel through solids, liquids, and gases.

Front

What does the 'P' in P Wave stand for?

Back

The 'P' in P Wave stands for 'Primary', indicating that these waves are the first to arrive during an earthquake.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's crust that move and interact with each other, causing earthquakes and volcanic activity.

Front

Where does the first movement occur during an earthquake?

Back

The first movement during an earthquake occurs at the 'Focus', which 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 seismic waves?

Back

Seismic waves are waves of energy that travel through the Earth, generated by the sudden release of energy during an earthquake.

Front

What is the difference between P Waves and S Waves?

Back

P Waves can travel through solids, liquids, and gases, while S Waves can only travel through solids.

Front

What is a fault in geology?

Back

A fault is a fracture or zone of fractures between two blocks of rock, which can cause earthquakes when the blocks move.

Front

What is the Richter scale?

Back

The Richter scale is a logarithmic scale used to measure the magnitude of earthquakes based on the amplitude of seismic waves.

Front

What is an aftershock?

Back

An aftershock is a smaller earthquake that occurs in the same area after a larger earthquake.
