About This Chapter
How It Works:
- Identify the lessons in the ScienceFusion Erosion & Deposition by Wind, Ice & Gravity chapter with which you need help.
- Find the corresponding video lessons with this companion course chapter.
- Watch fun videos that cover the erosion & deposition topics you need to learn or review.
- Complete the quizzes to test your understanding.
- If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.
You'll learn all of the geology topics covered in the textbook chapter, including:
- Effects of wind on deserts

1. Wind Action & Effects on the Desert Landscape
Wind is a powerful force that has the ability to shape a landscape. In deserts, wind action changes the landscape through wind erosion in the form of abrasion and deflation.
2. Sand Dunes: Structure and Types
Although most people think of sand dunes simply as piles of sand, they actually come in many different shapes and sizes. In this lesson, we'll discuss the unique features of barchan, transverse, parabolic, longitudinal and star sand dunes.
3. Glacial Erosion: Definition, Processes & Features
Glaciers are huge blocks of ice that move along the landscape, carving distinct features along the way. Learn about the glacial erosion processes, plucking and abrasion, and the features they create, including cirque, horns, arête and roche moutonnee.
4. Glacial Deposition: Definition & Results
As glaciers move and retreat, they push and drop rocks and sediments in a process known as glacial deposition. Learn about this glacial process and the interesting landforms that result from it, including moraines, erratics and drumlins, in this lesson.
5. 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.
