Chapter 4 Lesson 3&4 review

Leetha had been learning about volcanoes and how they form, but she wanted to know more about hot spots. How does a hot spot form a chain of volcanoes?

• A hot spot moves under the plate as the plate continues moving.

• A hot spot remains in a fixed place in the mantle, but the plate continues moving.

• The mantle is continuously moving, and the hot spot moves in the opposite direction.

• The crust is constantly moving, but at a slower pace than the hotspot.

High silica magma is more sticky and more likely to produce

• a lava plateau

• an explosive eruption

• shield volcano

• smooth flowing lava

What does the magnitude of an earthquake measure?

• he length of the earthquake

• the size of the earthquake’s seismic waves

• the energy released by the earthquake 

• the damage done by the earthquake 

Large waves are also caused by strong winds that blow over wide areas of ocean. How do tsunamis differ from waves caused by strong winds?

• A. Larger amounts of water are displaced by waves caused by the wind than by tsunamis.

• Tsunamis involve both deep water and surface water, but waves caused by wind involve only surface water

• Tsunamis involve only surface water, but waves caused by wind involve both deep water and surface water.

• Waves caused by wind carry more energy and are more destructive than tsunamis.

What boundary helped create the volcanoes in Icelanad 

• Convergent

• Divergent

• Transform

• Strike slip
