Unit 6 Lesson 6 Earthquakes

Which of the following events can produce an earthquake?

• the force of tsunamis in the oceans

• a sudden release of energy from the mantle

• movement of tectonic plates along a fault

• the violent shaking of sections of the lithosphere

Which type of stress causes deformation that leads to earthquakes at converging plate boundaries?

• tension

• stretching

• shear stress

• compression

Which of the following causes most of the human injuries during a major earthquake?

• car accidents caused by the ground shaking

• falling into large cracks that form in the ground

• violent winds caused by the rapid movement of the ground

• collapsing buildings and other structures caused by the ground shaking

Which claim explains why most earthquakes take place at tectonic plate boundaries?

• The rock in the interior of a tectonic plate is stronger, so it does not deform.

• Earthquakes take place where energy is transferred to rock by the motion of tectonic plates.

• Earthquakes can only occur at places where magma can reach the surface and transfer energy to rocks.

• Earthquakes take place when one plate moves over another plate, which happens only at plate boundaries.

The energy released by an earthquake is the result of elastic rebound. Which claim explains how elastic rebound takes place?

• Pressure builds on rocks until they suddenly collapse.

• Rocks that are stretched or compressed suddenly return to their previous shape

• Rocks gain energy from the constant pull of gravity and move when obstructions are removed

• Rocks begin to melt due to the heat of the mantle and suddenly crystallize when pressure is removed
