Seismic Waves

Front

What are seismic waves?

Back

Seismic waves are waves of energy that travel through the Earth, typically as a result of an earthquake or other geological activity.

Front

What are the two main types of seismic waves?

Back

The two main types of seismic waves are body waves and surface waves.

Front

What are Primary (P) Waves?

Back

Primary waves, or P waves, are the fastest type of seismic wave and can travel through solids, liquids, and gases.

Front

What are Secondary (S) Waves?

Back

Secondary waves, or S waves, are seismic waves that can only travel through solids and are slower than P waves.

Front

What are surface waves?

Back

Surface waves are seismic waves that travel along the Earth's surface and are typically responsible for the most damage during an earthquake.

Front

What is a seismograph?

Back

A seismograph is an instrument that detects and measures the intensity, duration, and direction of seismic waves.

Front

What is the order of seismic wave appearance during an earthquake?

Back

The order of appearance is P waves first, followed by S waves, and then surface waves.

Front

Can Primary (P) Waves travel through liquids?

Back

Yes, Primary (P) Waves can travel through solids, liquids, and gases.

Front

What is the difference between body waves and surface waves?

Back

Body waves travel through the Earth's interior (P and S waves), while surface waves travel along the Earth's surface.

Front

What is the focus of an earthquake?

Back

The focus is the point within the Earth where an earthquake originates.
