Exogenic processes originate externally to the Earth's surface and include weathering, erosion, mass wasting, and deposition. Weathering is the breakdown of rocks at the Earth's surface by temperature, rainfall, frost and other environmental factors. Erosion is the transport of weathered rock and sediment by forces like water, wind, glaciers and gravity. Mass wasting is the downward movement of rock and sediment on slopes due to gravity. Deposition occurs as eroded sediments are deposited in a new location through wind, water or other transport processes. Exogenic processes play an important role in shaping the Earth's surface and creating different landforms and landscapes.

1. Exogenic Processes
Definition and Types

2. Exogenic Processes:
 include geological phenomena and processes that
originate externally to the Earth's surface. They are
genetically related to the atmosphere, hydrosphere and
biosphere, and therefore to processes of weathering,
erosion, mass wasting, sedimentation, transportation,
deposition, denudation, etc.
 are processes that takes place at or near Earth’s surface
that makes the surface wear away. These processes are
very destructive, they are responsible for degradation and
sculpting the Earth’s surface.

3. Exogenic Processes have four main types;
Weathering, Erosion, Mass wasting,
Deposition

4. • Weathering
 Is the general term applied to the
combined action of all processes that
cause rock to disintegrate physically and
decompose chemically because of exposure
near the Earth's surface through the
elements of “weather” such as
temperature, rainfall, frost, fog and ice.

5. Factors of Weathering:

6. • Erosion
 In the most broad and common
meaning, erosion includes all exogenic
processes, in the absence of weathering
(which causes the breakdown of rock
material) and mass movements. Natural
agents of erosion include water, wind,
glaciers, snow, sea/lake waves, and gravity
(as a constant force on unstable slopes).

7. Factors of Erosion:

8. • Mass Wasting
 defined as the down slope movement of
rock and regolith near the Earth's surface
mainly due to the force of gravity. ... Mass-
wasting processes are occurring
continuously on all slopes; some mass-
wasting processes act very slowly, others
occur very suddenly, often with disastrous
results.

9. Factors of Mass Wasting:

10. • Deposition
 is the geological process in which
sediments, soil and rocks are added to a
landform or land mass. Wind, ice, water,
and gravity transport previously weathered
surface material, which, at the loss of
enough kinetic energy in the fluid,
is deposited, building up layers of
sediment.

11. Factors of Deposition:

12.  Exogenic processes (e.g., mass movement,
erosion, deposition, and weathering) play
an important role in the formation of relief
and create a variety of landscapes.
Exogenic processes may be destructive but
on good side it also help us on reshaping or
rechanging our surface.
