Question

2. Name two types of earthquake
wave. Difference between P - waves
and S waves
​

Answer 1

Explanation:

In seismology, the study of earthquakes, there are two main types of waves: p-waves and s-waves. P-waves, or primary waves, are longitudinal, where the earth compresses and stretches in the direction of wave propagation. S-waves, or secondary waves, are transverse, where the earth moves up and down as the wave travels

Answer 2

Answer:

P waves travel faster than S waves, and are the first waves recorded by a seismograph in the event of a disturbance. ... The S waves are the second wave to reach a seismic station measuring a disturbance. The difference in arrival times helps geologists determine the location of the earthquake.
