Erosion and Weathering Processes

The video tutorial explains how internal and external agents shape the Earth's surface over millions of years. It covers the processes of weathering, including physical, chemical, and biological types, and how these contribute to landscape transformation. The tutorial also discusses erosion and sedimentation, highlighting the roles of water, wind, and ice. Human activities are examined for their significant impact on landscapes, altering natural processes. The video concludes with a detailed look at various erosion types, such as fluvial, marine, and glacial, and their effects on the environment.
