(8) Chapter 4 Earthquakes

Stress that pushes a mass of rock in two opposite directions is called (side to side)

• tension

• compression

• shearing

• deformation

The point beneath the Earth's surface where the rock breaks under stress and triggers an earthquake is called the

• epicenter

• focus

• syncline

• footwall

A large flat area of land elevated high above sea level is a called a

• plateau

• hanging wall

• footwall

• canyon

What can cause damage days or even months after a large earthquake occurs?

• surface waves

• convcection

• tsunami

• aftershock

A fold in a rock that bends upward into an arch is called

• syncline

• anticline

• canyon

• plateau

In a normal fault, the part of the fault that lies below the other part is called the

• footwall

• hanging wall

• reverse fault

• anticline

____________ is the stress that causes reverse faults

• shearing

• tension

• compression

• deformation

When rocks on either side of the fault slip past each other with little up and down motions, this is a ___________ fault

• normal

• reverse

• strike-slip

• syncline

The rating system that estimates the total energy released by an earthquake is called the

• moment magnitude scale

• Richter Scale

• Mercalli Scale

• Seismograph Scale

The stress force that pulls on the crust where two plates are moving apart is called
