Forces which act in the interior of the earth are called as
A. Exogenic forces
B. Endogenic forces
C. Eurogenic forces
D. None of these

Hint: The lithosphere is divided into several plates known as lithospheric plates. These plates move very slowly - just millimeters a year, this is due to the flow of magma molten inside. The movement of these plates creates a change in the earth's surface. Movements of the Earth are divided on the basis of the forces that cause them.

Complete Answer:
Forces that gain power outside the Earth or arising from Earth's atmosphere are called exogenous forces or external forces. Sedimentation is the main exogenous process, and the elements of nature that can carry out these exogenous processes are called geomorphic factors.
Endogenic force or endogenetic force is also called internal force because it is the pressure generated inside the earth. These internal forces cause vertical and horizontal movements, including land subsidence, land uplift, volcanic activity, fault movements, folding, and earthquakes. These forces have a land altering capacity that plays an important role in the formation of the crust.
Therefore, the correct answer is Option, ‘B. Endogenic forces’.

Note: Endogenic movements are divided into two categories- Slow movements, that are also called Diastrophic forces, lead to a periodic change. Diastrophic forces can be defined as the force exerted by the movement of a solid object on the surface of the earth. Sudden movements are visible movements, and they involve major changes in the shape of the earth such as earthquakes and volcanic eruptions.
