Ch 10: Weathering, Erosion & Deposition

About This Chapter

Check out the video lessons in this chapter to explore the processes of weathering, erosion and deposition. Learn about the types of weathering in addition to the impact of deposition and erosion.

Weathering, Erosion & Deposition - Chapter Summary

This chapter's video lessons focus on the effects of weathering, erosion and deposition on landforms. Our experienced instructors explain the processes of chemical and mechanical weathering as well as the factors that lead to soil erosion. You'll also take a look at some of the many landforms created by the process of glacial deposition. Once you've studied the entire chapter, you should be able to do the following:

  • Recognize the impact of erosion and deposition on landforms
  • Give examples of mechanical and chemical weathering
  • Identify factors that affect the weathering rate
  • Explain how soil is formed
  • List causes of soil erosion
  • Describe the types of wasting
  • Define glacial erosion
  • Provide examples of landforms created by glacial deposition

With our brief video lessons available on mobile devices, you'll be able to learn about these earth science topics when and where it fits your schedule. Our videos are full of engaging graphics and straightforward explanations to help you retain important terms or concepts. We also provide video transcripts that often have links to other relevant lessons. After you've completed each lesson, take the self-assessment quizzes to check your grasp of the chapter material.

Effect of Erosion and Deposition on Landforms

1. Effect of Erosion and Deposition on Landforms

Landforms are constantly being broken down and reformed by the processes of weathering, erosion, and deposition. In this lesson, we explore chemical and physical weathering and how the face of the earth gets changed.

Mechanical Weathering: Definition, Process, Types & Examples

2. Mechanical Weathering: Definition, Process, Types & Examples

Over time, the forces of the natural environment cause rocks to physically break down in a process called mechanical weathering. Learn how factors, such as wind, water and temperature fluctuations lead to mechanical weathering.

What is Chemical Weathering? - Definition, Process & Examples

3. What is Chemical Weathering? - Definition, Process & Examples

Chemical weathering is what happens when rocks are broken down and chemically altered. Learn about the different types of chemical weathering, including hydrolysis, oxidation, carbonation, acid rain and acids produced by lichens.

Factors that Affect the Rate of Weathering

4. Factors that Affect the Rate of Weathering

Weathering is the process that breaks down rocks into smaller pieces. The rate at which rock weathers depends on certain factors. Learn how factors, such as exposure to the atmosphere, the composition of rock and climate affect the rate of weathering.

The Formation and Composition of Soil: Definition and Factors

5. The Formation and Composition of Soil: Definition and Factors

In this video lesson you will learn how soil is formed and what it is made of. You will also learn about how soil is classified and distributed in layers underground.

What is Soil Erosion? - Definition and Causes

6. What is Soil Erosion? - Definition and Causes

With soil erosion, the top layer of soil is worn away due to factors such as water, wind and tillage of farmland. Learn about soil erosion and how natural elements and human activities break up and transport soil.

Types of Wasting: Slump, Rockslide, Debris Flow & Earthflow

7. Types of Wasting: Slump, Rockslide, Debris Flow & Earthflow

Mass wasting is a type of erosion that results in the mass movement of rock, soil and debris down a slope. Learn about the different types of mass wasting, including slumps, rockslides, debris flows and earthflows.

Glacial Erosion: Definition, Processes & Features

8. Glacial Erosion: Definition, Processes & Features

Glaciers are huge blocks of ice that move along the landscape, carving distinct features along the way. Learn about the glacial erosion processes, plucking and abrasion, and the features they create, including cirque, horns, arĂȘte and roche moutonnee.

Glacial Deposition: Definition & Results

9. Glacial Deposition: Definition & Results

As glaciers move and retreat, they push and drop rocks and sediments in a process known as glacial deposition. Learn about this glacial process and the interesting landforms that result from it, including moraines, erratics and drumlins, in this lesson.
