Wind Action & Effects on the Desert Landscape

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.

Sand Dunes: Structure and Types

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.

Glacial Erosion: Definition, Processes & Features

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, arĂȘte and roche moutonnee.

Glacial Deposition: Definition & Results

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.

Mass Wasting: Definition, Types, Causes & Processes

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.
