Geomorphology is defined as a scientific study of geological features.
The genesis
as well as evolution of topographical features and landscapes comes under the
study of geomorphology.
The shape
and the structure of the geological features changes with respect to time due
to many physical, chemical and biological factors.
So this
change evolved from their time of origin is studied under the disciplines of
geomorphology.
Tectonic
activity plays an important role for the upliftment and subsidence of the
geological features which leads to origin of new landscape or topography.
Likewise the
tectonic activities, igneous intrusion or volcanic activities also form new
landform on the continental crust as well as in oceanic crust as a mid oceanic
ridge.
From tectonic to volcanism, geomorphology
includes every single process which helps to develop landform or structures on
the earth surface.
There are
many processes involved in the development of geological features/ landforms.
Landforms
may be developed by:
-Aeolian
process (by the action of wind)
-fluvial
process (by the action of water)
-igneous
process (by the action of magma/volcanism)
-tectonic
process (by tectonic movement), etc.
This
concludes that, geomorphology deals with the origin, identification and
geological evolution of landforms/ features.
