Main Driving Force of Exogenic Forces

There are various exogenic forces that shape the surface of the earth. These forces can be classified into two categories: solar and gravitational forces. However, the main driving force behind all the exogenic forces is gravitational force.

Gravitational Force

Gravitational force is the force of attraction between two bodies. It is the force responsible for the movement of planets around the sun and the moon around the earth. This force is also responsible for the movement of water in rivers and oceans.

Solar Forces

Solar forces are the forces that originate from the sun. The sun emits energy in the form of radiation, which is responsible for various exogenic forces such as erosion, weathering, and mass wasting.

Exogenic Forces

Exogenic forces are the forces that are responsible for shaping the surface of the earth. These forces can be classified into two categories: solar and gravitational forces.

Solar Forces

Solar forces include:

- Radiation: The sun emits energy in the form of radiation, which is responsible for the heating and cooling of the earth's surface. This heating and cooling cause expansion and contraction of rocks, resulting in weathering and erosion.

Gravitational Forces

Gravitational forces include:

- Earthquakes: Earthquakes are caused by the movement of tectonic plates. The movement of these plates is due to the force of gravity.

- Landslides: Landslides occur due to the force of gravity. When the force of gravity is greater than the strength of the rock or soil, it causes the rock or soil to slide down.

- Erosion: Erosion is the process by which soil and rock are removed from the earth's surface. This process is due to the force of gravity, which causes the soil and rock to move downhill.

- Weathering: Weathering is the breakdown of rocks due to exposure to the elements. This process is due to the force of gravity, which causes the rock to move downhill.

In conclusion, while solar forces do play a role in shaping the surface of the earth, the main driving force behind all the exogenic forces is gravitational force. This force is responsible for various exogenic forces such as earthquakes, landslides, erosion, and weathering.

Gravitational force.....to be precise there is no sole driving force behind all the exogenic forces(denudation).
All exogenic processes derive energy from atmosphere which is determined by the ultimate energy from the sun.
