The endogenic and exogenic forces can cause changes in the configuration of the surface of the earth and refer to as geomorphic processes.
The energy originating from within the earth is the main force behind endogenic geomorphic processes.
This energy is mostly produced by rotational and tidal friction, radioactivity, and primordial heat from the origin of the earth.
This energy due to geothermal gradients and heat flow from within induces diastrophism and volcanism in the lithosphere.
The energy emanating from within the earth is the main force behind endogenic geomorphic processes.
The earth movements are mainly of two types: diastrophism and sudden movements.
Diastrophism:
All processes that move, elevate or build up portions of the earth’s crust come under diastrophism.
Diastrophism is further classified into orogenic (involving mountain buildings), epeirogenic (upliftment or warping of large parts of the earth's crust), earthquake, and plate tectonic activities.
Sudden movements:
They cause considerable deformation over a short span of time and may be of two types: earthquakes and volcanoes.
