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

Erosion and deposition affect landforms through the movement of broken-down rock from place to place, and the laying down of broken rock. Explore the process and differences between mechanical and chemical weathering and learn about landforms and how erosion and deposition affect landforms.

Mechanical Weathering: Definition, Process, Types & Examples

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

Mechanical weathering can be defined as the breakdown of rocks due to natural forces like wind, water, cold, and heat. Explore the examples of the different types of mechanical weathering, including thermal expansion, frost shattering, plant activity, and abrasion affect rock formations.

What is Chemical Weathering? - Definition, Process & Examples

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

Chemical weathering in geology is the process by which rocks are slowly broken down through chemical reactions, often resulting in a different substance entirely. Explore the effects caused by the five main types of chemical weathering: hydrolysis, oxidation, carbonation, lichens, and acid rain.

Factors that Affect the Rate of Weathering

4. Factors that Affect the Rate of Weathering

There are several factors that affect the rate of weathering of rocks. Explore how these factors, including exposure to the atmosphere, the composition of rock, and the climate, all affect the rate of weathering.

The Formation and Composition of Soil: Definition and Factors

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

While the term 'soil' is often simply associated with dirt, it is actually a complex mixture of elements that has unique physical characteristics. Learn what soil really is and explore its layers and how different factors contribute to its formation.

What is Soil Erosion? - Definition and Causes

6. What is Soil Erosion? - Definition and Causes

Soil erosion is the process of topsoil degradation, often through weathering or agricultural practices. Explore a variety of environmental causes of soil erosion, and their respective impact on the landscape.

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

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

There are several types of wasting that demonstrate the effects of erosion. Learn about the types of mass wasting, including slumps, rockslides, debris flow, and earthflow, and explore some causes of mass wasting.

Glacial Erosion: Definition, Processes & Features

8. Glacial Erosion: Definition, Processes & Features

When land is in the way of a slowly moving glacier, it can experience glacial erosion. In this lesson, learn what glacial erosion is, how it works, and specific features of the process.

Glacial Deposition: Definition & Results

9. Glacial Deposition: Definition & Results

Glacial deposition is when sediment and rocks drop from land formations due to glacier movements. Learn more on this, glacial till and moraines, characterize glacial erratics, and describe the appearance of drumlins.
