Mass movement refers to the displacement of weathered materials (regolith) on a slope under the influence of gravity. It can also be described as the movement of rock materials from one location to another due to the force of gravity. Factors Affecting Mass Movement: 1) Slope Gradient: The steepness of the slope plays a crucial

Weathering refers to the process of rock disintegration and decay caused by weather forces such as frost, rain, and temperature changes. It involves the breaking down of rocks into smaller fragments due to the impact of weather and atmospheric factors. Weathering can be categorized into three types: physical, chemical, and biological weathering. Physical/Mechanical Weathering: This

Denudation refers to the process of reshaping and reducing the Earth’s surface through the actions of specific agents known as denudation agents.
