Question

Which statement describes a surface wave?

a) "Surface waves propagate through the core of the Earth."
b) "Surface waves cause the most severe shaking during earthquakes."
c) "Surface waves travel faster than body waves."
d) "Surface waves are less destructive compared to body waves."

Answer 1

Surface waves in an earthquake are the most destructive and cause severe shaking during earthquakes. They propagate along the Earth's surface in a rolling motion and can cause significant damage to buildings and structures.

Step-by-step explanation:

Surface waves in an earthquake are similar to surface waves on water. They are the most destructive seismic waves and cause the most severe shaking during earthquakes. Unlike body waves (P-waves and S-waves) that propagate inside the Earth, surface waves propagate along the Earth's surface and move in a rolling motion. These waves are slower than body waves but can cause significant damage to buildings and structures.
