Explain exogenic force using example
Answers
The processes which occur on earth's surface due to the influence of exogenic forces are called as exogenic processes or exogenic geomorphic processes.
Weathering, mass wasting, erosion, and deposition are the main exogenic processes.
Note: A process is a force applied on earth materials affecting the same.
Answer:
Forces that drive the Earth system derive their energy from a number of different sources. Exogenic processes are those driven by exogenic forces that primarily derive their energy from solar radiation. For instance, soil erosion is caused by the force of wind acting on bare ground. We can trace the energy that causes wind erosion to the receipt of solar radiation. How? Though we are jumping ahead ourselves, wind is a product of horizontal differences in pressure over distance caused by the unequal heating of the Earth's surface. Low pressure is created when heated air rises from the surface and then flows outward at a higher elevation. As air moves upward, the surface pressure decreases relative to the air around it. The variation in surface pressure causes air to move into the region of low pressure to replace that which is rising, thus creating a wind. Soil is detached when wind blows over an erodible surface. Water and glacial erosion are other examples of exogenic processes
