In this chapter, you'll learn the answers to questions including:
- What are the five geological settings for deserts?
- What characteristics are found in Southwestern deserts?
- How does wind affect desserts?
- What are the five types of sand dunes, and how are they structured?
- How do humans cause desertification?
1. Earth's Deserts: Definition, Distribution & Location
Imagine a place where rain rarely falls and plants and animals are specially adapted to survive. In this lesson, we'll learn why deserts form and how their location is determined by the atmosphere, the hydrosphere and geology.
2. Characteristics of the Deserts of the Southwestern United States
In this lesson, we'll discuss two very different types of deserts located in the Southwestern United States. The Colorado Plateau and the Basin and Range Province each have special characteristics and features that make them unique.
3. Wind Action & Effects on the Desert Landscape
Wind is a powerful force that has the ability to shape a landscape. In deserts, wind action changes the landscape through wind erosion in the form of abrasion and deflation.
4. Sand Dunes: Structure and Types
Although most people think of sand dunes simply as piles of sand, they actually come in many different shapes and sizes. In this lesson, we'll discuss the unique features of barchan, transverse, parabolic, longitudinal and star sand dunes.
5. Desertification Caused by Human Activity
The earth is constantly changing, and one very dramatic and important change is from fertile land to deserts. This process of desertification can occur naturally, but is often caused or accelerated by human actions. Humans can accelerate this process by overgrazing, poor irrigation techniques, diverting rivers, and deforestation. This large issue is a global problem that must be combated.
6. What is a Wind Vane? - Definition, Uses & Facts
Have you ever used a thermometer to determine the temperature outdoors? Probably. Have you ever used a wind vane? Probably not. Why, then, are they still seen in many places? In this lesson, you will learn about the wind vane's purpose and some of its history.
7. What is a Natural Bridge? - Definition & Formation
Did you know that there are some bridges that were made from just wind and water? Learn how in this lesson, along with where you can go to see some of them.
