Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow and transported to other locations. There are different types of erosion including wind, water, gravitational, and coastal erosion. Excessive erosion causes problems such as desertification, decreases in agricultural productivity, sedimentation of waterways, and ecological collapse.

2.  Is the process by
which soil and
rock are removed
from the Earth's
surface by natural
processes such as
wind or water
flow, and
then transported
and deposited in
other locations.

3.  Excessive erosion
causes problems such
as desertification,
decreases in
agricultural
productivity due to
land
degradation, sedimenta
tion of waterways,
and ecological collapse

5.  There are different types of
erosion:
 Wind erosion,
 Water erosion,
 Gravitational erosion,
 Coastal erosion

7.  Wind erosion is a major force,
especially in arid and semi-
arid regions. It is also a major source
of land degradation, evaporation,
desertification, harmful airborne dust,
and crop damage—especially after
being increased far above natural rates
by human activities such
as deforestation, urbanization,

9.  Shoreline erosion, which occurs
on both exposed and sheltered
coasts, primarily occurs through
the action of currents
and waves but sea level (tidal)
change can also play a role.

11.  Water erosion is the transport of
loosened soil particles by surface
runoff that is flowing downhill in
thin sheets.
