What is a fault in geology?

Back

A fault is a fracture or zone of fractures between two blocks of rock.

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

Back

P-waves are primary waves that travel fast and can move through solids, liquids, and gases, while S-waves are secondary waves that travel slower and can only move through solids.
