Earthquake and Tsunami Hazards

The type of stress that pulls on and thins an area of Earth's crust is called

• torsion

• tension

• shearing

• diverging

When a plate is compressed, it can create anticlines and synclines that can become

• mountains and valleys

• folds and breaks

• plateaus and canyons

• landmasses and oceans

Stress that pushes masses of rock in opposite directions, in a sideways movement.

• stress

• shearing

• tension

• scale

Stress that squeezes rock until it folds or breaks.

• compression

• shearing

• stress

• earthquake

Which type of plate boundary is most associated with normal faults?

• convergent

• strike-slip

Tsunamis are caused by

• underwater disturbances such as earthquakes, landslides, and volcanoes.

• wind and the gravitational pull of the moon.
