Ch 6 Earthquakes

What are the three main types of stress in rock?

How does tension change the shape of the Earth’s crust?

• It stretches, or pulls, on the crust.

• It squeezes the crust.

How does compression change the shape of the Earth’s crust?

• It stretches, or pulls, on the crust.

• It squeezes the crust.

What is a fault?

Why do faults often occur along plate boundaries?

• Because friction happens there.

• Forces of plate motion pull and pull the crust so it breaks.

• Transform boundaries move away and cause them.

What type of fault is formed when plates diverge, or pull apart?

What type of fault is formed when plates are pushed together?

5 kinds of landforms formed by plate movement.

• fault, syncline, fold mountains, fault-block mountains, plateaus

• anticline, footwall, fold mountains, fault-block mountains, plateaus

• anticline, syncline, fold mountains, fault-block mountains, plateaus

• anticline, syncline, fold mountains, fault-block mountains, hangwall

What are 3 landforms produced by compression in the crust?

• anticline, syncline, fault-block mountains

• anticlines, synclines, plateaus

• anticline, syncline, folded mountains

What landform is produced by tension?

• folded mountains

• plateaus

• fault-block mountains
