Explain primary process involved in denudations with examples

Denudation is the process of wearing away or removing the top layer of rocks or soil from the Earth's surface. It involves several primary processes, including weathering, erosion, transportation, and deposition.

1. Weathering: This is the first step in the denudation process. Weathering involves the breakdown of rocks and minerals on the Earth's surface due to various factors like temperature changes, rain, wind, and biological activity. For example, in a desert, the extreme temperature changes can cause rocks to crack and break down, a process known as thermal weathering.

2. Erosion: After weathering, the next step is erosion. Erosion is the process by which the weathered rock particles are carried away from their original location. This can occur through natural agents like water, wind, ice, and gravity. For instance, a river can erode the banks and bed, carrying away the weathered material.

3. Transportation: This is the movement of the eroded material from one place to another. The agents of erosion like wind, water, and ice also act as agents of transportation. For example, a river can transport eroded material downstream, depositing it when the river's speed decreases.

4. Deposition: The final step in the denudation process is deposition. This is when the transported materials are deposited or laid down in a new location. For example, when a river enters a lake or the sea, its speed decreases, and it deposits the sediment it was carrying. This can lead to the formation of features like deltas and alluvial fans.

These processes of denudation continuously shape and reshape the Earth's surface, leading to the formation of various landforms.
