What is deformation in the context of geology?

Back

The bending, tilting, and breaking of the Earth's crust; the change in shape of a rock in response to stress.

Front

What is a fault in geological terms?

Back

A fracture or zone of fractures between two blocks of rock.

Front

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

Back

P-waves (primary waves) are compressional waves that travel faster and can move through solids and liquids, while S-waves (secondary waves) are shear waves that can only move through solids.
