About This Chapter
Below is a sample breakdown of the Deserts & Wind chapter into a 5-day school week. Based on the pace of your course, you may need to adapt the lesson plan to fit your needs.
|Day||Topics||Key Terms and Concepts Covered|
|Monday||Desert locations||The relationship between desert location, the atmosphere and the hydrosphere; distribution of the Earth's deserts|
|Tuesday||Deserts of the Southwestern U.S.||Mesas, buttes and monoclines of the Colorado Plateau; alluvial fans, bajadas, pediments and playas of the Basin and Range Province|
|Wednesday||Desert winds||Wind abrasion and the creation of ventifacts and pedestal rocks, deflation and the creation of blowouts and desert pavement|
|Thursday||Sand dunes||Characteristics of barchan, transverse, parabolic, longitudinal and star dunes|
|Friday||Desertification||Effects of overgrazing and deforestation, efforts to combat 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.
