Erosion's Impact on Landforms and the Role of Water

The video from FreeSchool explores how various landforms on Earth, such as mountains, deserts, and plains, are constantly changing due to erosion, primarily caused by water. It explains how water, in its liquid and solid forms, shapes landscapes through processes like ocean waves eroding coastlines, rivers carving paths like the Grand Canyon, and glaciers forming valleys and fjords. The video emphasizes the significant impact of water on Earth's surface, highlighting that even small amounts can lead to substantial changes.
