Landforms and Geological Processes

The video tutorial discusses external factors that cause changes on Earth's surface, focusing on denudation, which includes weathering, erosion, and deposition. It explains how different agents like water, wind, and glaciers contribute to these processes, leading to the formation of various landforms such as valleys, deltas, and dunes. The tutorial also highlights specific examples like the Ganga and Brahmaputra delta, the largest in the world.
