What type of fault will cause the hanging wall to move down

relative to the foot wall

Normal Fault

Rubbing two pieces of rock together causes this kind of deformation

Shearing

Hanging wall moves up relative to the footwall in a ________fault

Reverse

Rock bending into layers

Folding

Landmasses increasing in elevation over time

Rising of landmasses

Type of mountain formed by blocks of rocks uplifted by normal fault.

Fault-block

Break or crack along which rocks move

Fault

Makes up the Earth’s landmasses

Continental

Deformation that is a trash compactor

Compression

Block of rock above the fault

Hanging wall

When compression causes the hanging wall to slide over foot wall

Thrust fault

Layers of rock that form an arch shape

Anticline

Rock under this type of stress becomes thinner in the middle than at the ends

Tension

Formed when fluid collects beneath the Earth surface

Domes

Rocks undergo ____ they slowly change shape and volume

Stress

Foot wall is the block of rock that is _____ the fault.

Below

Floating crust exerts a downward force and the mantle exerts upward force is called _______

Isostasy

Million tons of sediment deposited into one area but the water level remains the same is called _____

Sinking of landmasses

Average depth of oceanic crust

8 kilometers

Causes rocks to break, tilt, and fold under stress

movement

Breaking, tilting, and folding of rocks

Deformation

Four factors that determine if a rock will fold or fault

Temperature

Pressure

Rock type

Stress
