Match the correct type of stress with the correct type of fault created by that stress.                                                                  Shearing is found at a _________________.

• Normal Fault

• Reverse Fault

• Strike-Slip Fault

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

• anticline

• syncline

• plateau

A fold that bends upward into an arch that is created by compression.

• syncline

• anticline

• plateau

This is a stress force that pulls on the crust, stretching the rock.

• compression

• shearing

• tension

This is a stress force that pushes masses of rock in opposite directions.

• compression

• shearing

• tension
