Ch 67: NMTA Social Science: Weathering & Erosion

About This Chapter

Brush up on weathering and erosion concepts to prepare for the NMTA Social Science test. Using our video lessons, refresh your memory of the types of weathering along with the causes and effects of soil erosion.

NMTA Social Science: Weathering & Erosion - Chapter Summary

If you're having trouble remembering key facts about weathering and erosion, let our experienced instructors and fun video lessons help you out. Watching these lessons on topics like mechanical weathering and erosion prevention prepares you for some of the questions you'll face on the NMTA Social Science test. Once you've studied this chapter, you should be able to do the following:

  • Explain the process of mechanical weathering
  • Define chemical weathering
  • Identify factors that impact the rate of weathering
  • List causes and effects of soil erosion
  • Describe soil erosion prevention methods

As long as you have a mobile device, you can watch our video lessons wherever you are. Typically lasting less than 10 minutes, the videos are packed with engaging graphics and clear explanations of important concepts. The lessons also include transcripts and self-assessment quizzes to further help you during study time.

Objectives of the NMTA Social Science: Weathering & Erosion Chapter

The weathering and erosion material covered in this chapter are addressed in the geography and culture content domain of the NMTA Social Science test, which is an exam required of those seeking New Mexico licensure as social science teachers in the K-12 system. The geography and culture section, which accounts for roughly 19% of your total score, is one of five content domains on the computer-based test.

This portion of the exam includes questions on human-environment interactions, geography terminology and human systems. When you complete the multiple-choice lesson quizzes included in this chapter, you'll be answering questions in the same format as those on the NMTA test.

Mechanical Weathering: Definition, Process, Types & Examples

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.

What is Chemical Weathering? - Definition, Process & Examples

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.

Factors that Affect the Rate of Weathering

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.

What is Soil Erosion? - Definition and Causes

4. 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.

Soil Erosion: Effects & Prevention

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.
