Seismic waves test questions - WJEC

1

Which type of seismic waves are transverse waves?

2

Which type of seismic wave travels the slowest?

3

Which type of seismic wave causes the most damage?

4

What do seismic P waves travel through?

5

The diagram below shows the path of which type of seismic wave through the Earth?

Diagram showing the curved path of seismic waves through the Earth. They travel through the mantle but cannot pass through the liquid outer core.

6

What is the name of the region of the Earth indicated here?

Diagram showing a cross-section of the Earth's structure. The region indicated is below the crust and above the liquid outer core.

7

If P waves travel at a speed of 8 km/s and S waves travel at a speed of 3 km/s, calculate the time lag between the arrival of P and S waves at a seismometer that is 500 km away.

8

What causes seismic waves to travel in curved paths?

9

What is the result of a greater distance between the earthquake and the seismometer?

10

What evidence do we have that the Earth has a liquid core?
