Why is it important to study glaciers and their impact on Earth's landscape?

Multiple Choice

Which of the following statements best describes the difference between valley glaciers and ice sheets?

• Valley glaciers are smaller and flow down mountain valleys, while ice sheets are enormous and cover large regions such as Antarctica and Greenland.

• Valley glaciers are found only at the poles, while ice sheets are found only at the equator.

• Valley glaciers are made of liquid water, while ice sheets are made of snow.

• Valley glaciers move faster than ice sheets and cover more land area.

How long will the water flow in this desert stream after a heavy rain shower?

Multiple Choice

How do floods differ between deserts and humid regions?

• Floods in deserts are usually short-lived and cause rapid erosion, while floods in humid regions last longer and subside slowly.

• Floods in deserts last longer than in humid regions.

• Floods in humid regions cause more erosion than in deserts.

• Floods in deserts are less dangerous than those in humid regions.

Multiple Select

Which of the following are ways wind erodes land surfaces in deserts?

• Deflation

• Abrasion

Multiple Choice

What is desert pavement and how does it form?

• A tightly packed layer of coarse particles left after wind removes finer particles through deflation.

• A type of sand dune formed by wind.

• A layer of fertile soil deposited by rivers.

• A result of water erosion in humid regions.

Open Ended

Explain how sand dunes migrate and what causes the formation of cross-beds in dunes.

Multiple Choice

Which factors determine the shape of a sand dune?

• Temperature and humidity

• Rainfall and soil type

• Presence of animals
