19.5 Essay Questions

1) Explain how circulation patterns in the atmosphere generate the bands of low-latitude deserts

around the Equator.

2) How can cold coastal currents along the west coasts of continents generate subtropical

deserts?

3) Compare and contrast major floods in a humid environment (i.e. along the Mississippi River)

against those in a desert environment.

4) Explain how the environmental conditions in the headwaters of the Colorado River affect the

longevity of the river as it moves through the desert.

5) What are the three stages of desert landscape evolution? Provide examples of landforms for

each.

6) Compare and contrast sediment transportation by wind and by water.

7) What role (if any) will our changing climate play in future desertification?

5)

Explain what happened in this figure.

6)

What feature is present in this image?

7)

Using this image, indicate the height to which wind was transporting sediment to abrade

Mushroom Rock.
