Ch 19: Geomorphology of Arid Regions

About This Chapter

The short and engaging video lessons in this chapter are designed to help middle school students learn more about geomorphology and arid regions. They can explore videos about deserts and sand dunes and take lesson quizzes to assess their comprehension of the materials.

Geomorphology of Arid Regions - Chapter Summary

Use the video lessons in this chapter to help your middle school students better understand geomorphology and arid regions. In this chapter, students can watch the short lessons to examine deserts and their characteristics, as well as how the earth's deserts are distributed and how desert landforms are shaped by wind. The lessons also help students identify five geologic settings for deserts, analyze why human activity sometimes causes desertification and explore the characteristics of deserts in the Southwestern United States. Lesson quizzes are available to assess how well your students understand the materials. Links are featured in the quizzes that allow students to jump to specific topics on the videos.

Earth's Deserts: Definition, Distribution & Location

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.

Characteristics of the Deserts of the Southwestern United States

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.

Wind Action & Effects on the Desert Landscape

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.

Sand Dunes: Structure and Types

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.

Desertification Caused by Human Activity

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.
