Front

Define a fault in geology.

Back

A fault is a fracture or zone of fractures between two blocks of rock, allowing for relative movement.

Front

What is a normal fault?

Back

A normal fault occurs when the hanging wall moves down relative to the footwall, typically due to extensional stress.

Front

What is a reverse fault?

Back

A reverse fault occurs when the hanging wall moves up relative to the footwall, typically due to compressional stress.

Front

What is a strike-slip fault?

Back

A strike-slip fault is a type of fault where the movement is horizontal, with blocks sliding past each other.

Front

What is the difference between tension and compression in geological terms?

Back

Tension pulls rocks apart, while compression squeezes rocks together.
