Ch5 S1 Forces in Earth’s Crust

Stress that pushes a mass of rock in two opposite directions. It can cause rock to break and slip apart or to change its shape.

• Compression

• Fault

• Shearing

• Stress

• Tension

A force that acts on an area of rock to change its shape or volume.

• Compression

• Fault

• Tension

A type of stress that squeezes rock until it folds or breaks.

• Tension

A type of stress that pulls on the crust, stretching rock so that it becomes thinner in the middle.

• Tension

A break in the rock of the crust where rock surfaces slip past each other.

• Compression

A large area of flat land elevated high above sea level.

• Hanging wall

• Normal fault

• Plateau

• Reverse fault

• Strike-slip fault

The block of rock that lies above in a Normal Fault.

• Hanging wall

• Normal fault

• Plateau

• Reverse fault

• Strike-slip fault

Found in places where plates move past each other, shearing the rocks. The rocks in this fault slip past each other with little up and down motion.

• Hanging wall

• Normal fault

• Plateau

• Reverse fault

• Strike-slip fault

The rock that lies below in a Normal Fault.

• Footwall

• Hanging wall

• Normal fault

• Reverse fault

• Strike-slip fault

Found in places where the rock of the crust is pushed together. It has similar structures but the blocks move in the opposite direction as in a Normal Fault.

• Hanging wall

• Normal fault

• Plateau

• Reverse fault

• Strike-slip fault
