Erosion Creates Landforms
2018-02-05
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.
