Earthquake waves-S and P waves

Front

What are P waves?

Back

P waves, or primary waves, are seismic waves that compress and expand the material they move through. They are the fastest seismic waves and can travel through solids, liquids, and gases.

Front

What are S waves?

Back

S waves, or secondary waves, are seismic waves that move the ground up and down or side to side. They are slower than P waves and can only travel through solids.

Front

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

Back

The main difference is that P waves can travel through solids, liquids, and gases, while S waves can only travel through solids.

Front

What are body waves?

Back

Body waves are seismic waves that travel through the interior of the Earth. They include both P waves and S waves.

Front

What are surface waves?

Back

Surface waves are seismic waves that travel along the Earth's surface. They are slower than body waves and typically cause more damage during an earthquake.

Front

What are compression waves?

Back

Compression waves are waves that cause particles in a medium to move closer together. P waves are an example of compression waves.

Front

What are the characteristics of P waves?

Back

P waves are longitudinal waves, they travel faster than S waves, and they can move through all states of matter (solid, liquid, gas).

Front

What are the characteristics of S waves?

Back

S waves are transverse waves, they travel slower than P waves, and they can only move through solids.

Front

What is the speed comparison between P waves and S waves?

Back

P waves travel faster than S waves, typically at speeds of about 6-8 km/s, while S waves travel at about 3-4 km/s.

Front

What happens to P waves when they encounter a liquid?

Back

P waves can pass through liquids, which is why they are detected by seismographs even when they travel through the Earth's liquid outer core.
