About This Chapter
Weathering & Erosion - Chapter Summary
The lessons in this chapter will help you refresh your knowledge of weathering, soil erosion and mass wasting. You'll examine the defining characteristics of each process and look at the causes. After watching all these videos, you should be informed about:
- Types, causes and rates of weathering
- Causes and prevention methods of soil erosion
- Types and processes of mass wasting
- Triggers for mass wasting, such as vegetation removal or earthquakes
- Types of mass wasting, including rockslides and slump
You can watch these brief instructional videos, each about five minutes long, on a computer, smartphone or tablet, anywhere you have access to the Internet. After each lesson is a short multiple-choice quiz that lets you assess your learning. If something is still unclear, use the embedded video tags to return to that topic in the lesson.
1. Weathering: Definition, Types, Causes & Rates
Ever wondered how erosion could create something as dramatic as the Grand Canyon? The simple answer is weathering. This lesson describes the three major types of weathering, their causes, and how weathering rates can change.
2. Soil & Erosion: Definition, Types, Causes & Prevention
One of the most important things that we can do to ensure the health of our crops and nearby ecosystems is to reduce erosion. This lesson explains the relationship between soil and erosion, as well as ways to stop erosion.
3. 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.
4. 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.
5. 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.
