Seismic waves

The video tutorial explains seismic waves, which originate from earthquakes or other vibrations. It describes different types of seismic waves, including P waves, which are fast-moving compression waves traveling underground, and slower transverse waves that travel both underground and at the surface.

What is a common source of seismic waves?

• Flood

• Volcanic eruption

• Tornado

• Earthquake

Which type of seismic wave is known for its fast speed and compression nature?

• S waves

• P waves

• Surface waves

• Rayleigh waves

How do P waves primarily travel?

• In water

• Through the air

• On the surface

• Underground

What is a characteristic of transverse waves?

• They are compression waves

• They are the fastest seismic waves

• They travel only on the surface

• They are slower and travel both underground and at the surface

Where can transverse waves travel?

• Only underground

• Only at the surface

• Only in the ocean

• Both underground and at the surface
