Question

What are exogenic & endogenic forces?

Answer 1

Hint: The pressure that originates within the planet, contributes to vertical and horizontal motions, resulting in subsidence, land up-liftment, volcanism, faulting, bending, earthquakes, etc.

Complete Solution Step by Step
Endogenic forces
1. Forces working within the earth’s surface are called endogenic forces.
2. Endogenic forces are the pressure within the earth, also known as internal forces. Such internal forces contribute to vertical and horizontal motions and lead to subsidence, land upliftment, volcanism, faulting, folding, earthquakes, etc.

Important Feature of endogenic force -
1. Volcanism, folding, and faulting are the key mechanisms involved in this.
2. The development of this energy results from primordial heat, radioactivity, tidal and rotational friction from the ground.
3. These are also called internal pressure as they form, originate and are located below the surface of the earth.
4. The development of this energy results from primordial heat, radioactivity, tidal and rotational friction from the ground.

Exogenic forces
The forces acting above the surface of the earth are known as exogenous forces.
Exogenic forces are a direct consequence of stress caused by various forces in Earth materials that come into being due to the heat of the sun. They can face shear stresses, caused by temperature changes that break rocks and other earth materials or molecular stresses.

Important Feature of Exogenic force –
1. All exogenous processes are covered by denudation, meaning strip off or expose, under a general phrase.
2. Exogenic processes or exogenic geomorphic processes are the processes that occur on the surface of the earth due to the effect of exogenous forces.
3. The main exogenous processes are weathering, mass wasting, erosion, and deposition.
Due to gradients, all changes occur within the planet or on the earth's surface, from higher levels to lower levels, from high pressure to low pressure, etc.
4. The exogenous forces derive their energy from the atmosphere, determined by the sun 's ultimate energy and also the gradient generated by tectonic factors. In previous papers, we have already addressed that slopes on the surface of the earth are primarily produced by tectonic influences or motions of the earth due to endogenous forces.

Note
It is possible to distinguish endogenic forces as slow movements (diastrophic) and sudden movements. Very gradually, slow movements produce changes that may not be visible during a human lifespan.
The action of exogenous forces results in wearing down and are thus known to be forces of land wearing.
