About This Chapter
Weathering, Erosion & Wasting- Chapter Summary
To learn more about weathering, erosion and wasting, work through the entertaining video lessons in this chapter. You can review topics topics like mechanical weathering, mass wasting and soil erosion. By reviewing this chapter, you should develop the knowledge to do the following:
- Detail the different types of mechanical weathering
- Give examples of chemical weathering
- Understand various factors that impact the rate of weathering
- Recall the types of soil
- Explain ways soil erosion can be prevented
- Describe types of mass wasting
- Identify the triggers that result in mass wasting
- List various types of wasting, such as rockslides and earthflows
The video lessons are short in length, yet engaging and fun. Each video is paired with a written transcript that has terms and keywords in bold print for emphasis. When you are ready, you can take the lesson quizzes to test yourself on these weathering and erosion topics. The quizzes let you know what your strengths and weaknesses are and include quick links back to the corresponding topics within the lessons for easy review.
1. 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.
2. 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.
3. 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.
4. What is Soil? - Definition, Structure & Types
Soil is the material found on the surface of the earth that is composed of organic and inorganic material. Soil varies due to its structure and composition. Learn about the different types of soil and soil structures in this video lesson.
5. Soil Erosion: Effects & Prevention
Topsoil is lost through soil erosion. This can reduce soil quality and cause water pollution. Learn about the effects of soil erosion as well as preventative measures, including increased vegetation, terracing, crop rotation and strip cropping.
6. Mass Wasting: Definition, Types, Causes & Processes
Mass wasting or mass movement is the movement of a large mass of rock, soil and debris downward due to the pull of gravity. Learn about the process of mass wasting, the factors that must be present to trigger it and the different types.
7. Major Triggers for Mass Wasting: Water, Slopes, Vegetation Removal & Earthquakes
Mass wasting is the movement of mass amounts of rock, soil and debris downward due to gravity. Learn about major triggers of mass wasting, such as increased water, increased slope steepness, the removal of vegetation and earthquakes.
8. 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.
