Eroding Soil: Types of Soil Erosion

Learning Objective

At the end of the lesson, you will be able to describe different types of soil erosion.

Introduce the learning objective and let students know what they will be able to do by the end of the lesson.

What do you already know about soil erosion?

What is Soil Erosion?

Soil erosion is the process by which soil is transported from one location to another by wind, water, or other natural forces.

Introduce the concept of soil erosion and provide examples of natural forces that cause it.

Types of Soil Erosion

There are three main types of soil erosion: sheet erosion, rill erosion, and gully erosion.

Describe the three main types of soil erosion and provide visual aids to help students understand the differences between them.

Sheet Erosion

Sheet erosion is the gradual removal of soil from a surface by water flowing over it.

Explain how sheet erosion occurs and provide examples of areas where it is common.

Rill Erosion

Rill erosion is the removal of soil by concentrated water running through small channels or depressions in the soil.

Describe how rill erosion occurs and provide visual aids to help students understand the process.

Gully Erosion

Gully erosion is the removal of soil by concentrated water running through larger channels or deep depressions in the soil.

Explain how gully erosion occurs and provide examples of areas where it is common.

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.

What is soil erosion?

1. The process of soil being removed by water or wind.
2. The process of soil being added to by water or wind.
3. The process of soil being compacted by water or wind.
4. The process of soil being heated by water or wind.

What are the three main types of soil erosion?

1. Rill erosion, trench erosion, and channel erosion.
2. Surface erosion, subsurface erosion, and wind erosion.
3. Sheet erosion, rill erosion, and gully erosion.
