Open Ended

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.
