Weathering and
Erosion
Weathering
Weathering - the process that breaks
down rocks into smaller pieces
The 3 types of weathering
Physical Weathering (mechanical)
Chemical Weathering
Biological Weathering
Weathering
Physical Weathering (mechanical) - is
weathering that is caused by a physical
force. This can be caused by water, ice,
and wind.
Ice
Water
Wind
Weathering
Chemical Weathering - Occurs when there is
a chemical reaction between water, air, or
another substance and the material in rocks. This
can be caused by water and air.
Air
Weathering
Tress and
Plants
Biological Weathering - Weathering
(physical or chemical) that is caused by
living things.
Lichens & Moss
Animals
Erosion
Erosion _ the movement of weathered
rock material from once place to
another
Erosion can be fast process or a slow one that occurs
over thousands of years
Erosion can be caused by…
Glaciers (Ice)
Running Water
Waves
Wind
Gravity
Erosion
Glaciers (Ice) – A slowly moving mass or
river of ice formed by the accumulation and
compaction of snow on mountains or near
poles.
Glaciers move downhill and because their massive
size and power they can carve away big chunks of
land
Glaciers can cause
significant

Erosion
Glaciers (Ice)
As you can see
glaciers can
carve away
land
Erosion
Running Water – As water flows over land
it can remove rocks as well as to carve
huge chunks of land
Erosion
Waves – When waves hits rocks because
of the strength and power they have they
can break rocks or move rocks. it can
cause erosion
Erosion
Waves
Erosion
Wind – Wind carry's away sediment from
one place to another (long distances)
When winds stops going
fast is when the sediment
goes back to the ground
Wind
Erosion
Erosion
Gravity – Can cause large chucks of land
to fall downhill
Erosion
Erosion
Erosion
Deposition – The settling of eroded rock
material on Earth’s surface
How do they work together to
affect rocks?
This two work together because at the
beginning its a big normal rock then water,
ice, wind, and temperature hit the rock and
that process makes it brake down into
smaller pieces. Days, weeks months, or
even year go on a then glaciers, running
water, waves wind, and gravity hit the
smaller pieces of rock and moves them
from one place to another.
