Earthquake Review

The forces produced by the movement of Earth's plates can fold, stretch, and uplift the crust

Bends in rock that form when compression shortens and thickens part of Earth's crust

A fold in a rock that bends downward to form a valley

Seismic waves that move rocks up and down like a wave in a rope

Tension in Earth's crust pulls rock apart, causing which type of fault
