Weathering is the breaking down of rocks by
physical or chemical processes. For example, water freezing in a crack in the
ground and breaking the ground up into smaller pieces.
Physical
Action – the wind and water disintegrate the rocks
Chemical
Action – acids in the water dissolve the rock into particles
(Eg –
sinkholes are where the limestone dissolves underneath the surface of the earth
creating a cavern, which eventually will cave in causing a giant hole in the
ground.)
Erosion
is the wearing away of
the earth’s surface by wind, water or glacial action. For example, how the
moraines were formed in the Kitchener/Waterloo area (the hills formed from the
last ice age). Also, can be seen clearly at a shoreline.
