Chapter 4 Review: Earthquakes

Stress that moves a mass of rock in two opposite directions is called

• Shearing

• Compression

• Tension

• Deformation

Answer explanation

Tension Pulls a rock apart, with each end going in opposite directions

Which of the following can cause damage days or months after a large earthquake?

• The Arrival of Surface Waves

• A Tsunami

• Convection

• An Aftershock

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

• Hanging Wall

• Footwall

• Reverse fault

• Anticline

In a strike-slip fault, the rocks on either side of the fault slip past each other sideways with little

• Noise

• Up-or-down Motion

• Shaking

• Movement

Which type of stress force produces reverse faults?

• Shearing

• Compression

• Tension

• Deformation

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

• Anticline

• Plateau

• Syncline

• Canyon

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

• Syncline

• Canyon

• Plateau

• Fault

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

• Syncline

• Epicenter

• Footwall

• Focus

The type of seismic waves that arrive at the surface first and move by compressing and expanding the ground like an accordion are called

• S waves.

• Surface waves.

• P waves.

• Mercalli waves

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

• Richter scale

• moment magnitude scale.

• mechanical seismograph scale.

• Mercalli scale.

Answer explanation

The Mercalli scale rates damage. The Richer scale rates the size of the waves. The moment Magnitude scale rates the amount of energy released by an Earthquake
