Weathering, Erosion, and Deposition

The video tutorial explains the processes of weathering, erosion, and deposition, which have shaped Earth's landscapes over billions of years. Weathering breaks down rocks into smaller pieces through agents like rain and wind. Erosion involves the movement of these materials by rivers, glaciers, and wind, sculpting features like the Grand Canyon. Deposition occurs when these materials settle, forming landforms such as sand dunes and limestone layers. These processes have been crucial in developing the landforms we see today.
