Unit 4 Geosphere Part 2 Test

Front

What type of force is involved with a compression fault?

Back

Compression is the type of force that pushes rocks together, causing them to deform.

Front

How does a heavy rainstorm affect the volume of water and rate of erosion in a stream?

Back

Both the volume of water and the rate of erosion will increase after a heavy rainstorm.

Front

What is shearing stress?

Back

Shearing stress is the stress that pushes masses of rock in opposite directions, causing a sideways movement.

Front

What type of fault is characterized by the hanging wall moving down relative to the footwall?

Back

A normal fault is characterized by the hanging wall moving down relative to the footwall.

Front

What does it mean when we say the intensity of an earthquake is greatest at a location?

Back

It means that the effects of the earthquake, such as shaking and damage, were most severe at that location.

Front

What is the difference between magnitude and intensity of an earthquake?

Back

Magnitude measures the energy released at the source of the earthquake, while intensity measures the effects of the earthquake at different locations.

Front

What type of stress causes a normal fault?

Back

Tension stress causes a normal fault by pulling rocks apart.

Front

What is a strike-slip fault?

Back

A strike-slip fault is a type of fault where rocks slide past each other horizontally.

Front

What happens to the rate of erosion when the volume of water in a stream increases?

Back

The rate of erosion typically increases when the volume of water in a stream increases.

Front

What is the role of gravity in the movement of rocks along faults?

Back

Gravity can influence the movement of rocks along faults, especially in normal faults where it pulls the hanging wall down.
