Earthquakes and Faults

Which of the following describes a fault?

• An energy released from the inside of the Earth.

• A movement in the Earth’s crust.

• A break in the Earth’s crust.

• A rock layer.

What occurs when faults move?

• volcanic eruption

• earthquake

• landslide

• drought

Why is it that not all movements along faults produce earthquakes?

• It is because the energy of the Earth that causes the rocks to move is very strong enough.

• It is because the friction between rocks was not overcome by the energy of the Earth.

• It is because there is no friction present between the rocks.

• It is because the layers of rocks were not broken.

Fault movement is always associated with earthquakes. Arrange the following events how fault movements generate earthquakes. I. Once friction is overcome, the rocks suddenly slip. II. Ground suddenly moves and an earthquake occurs. III. Energy from inside the Earth is necessary to make the ground move. IV. The rocks are stuck together due to friction.

• I, II, III, IV

• II, IV, I, III

• III, IV, I, II

• IV, II, I, III

How do faults produce earthquakes?

• Energy from inside the Earth makes the ground move, once friction is overcome, a fault slips producing an earthquake.

• Rock materials from underneath go out along faults produces earthquakes

• Magma spreads beneath the rock layers producing faults.

• Tectonic plates collide producing earthquakes.
