Weathering and Erosion: What Is Weathering?

The video explains erosion, a process where earth materials like rocks and soil are moved by agents such as water, wind, and glaciers. Water is highlighted as the most powerful agent, transporting sediments through rivers and waves. Wind can move sand to form dunes, while glaciers carry rocks and debris as they move. The video provides examples like the Mississippi River and Death Valley to illustrate these processes.
