Geomorphic processes
Weathering
-
breakdown of material in a fixed place
.
Mechanical weathering-
the physical actions of rain, frost and wind that create weaknesses in rocks.
Chemical weathering-
Minerals can react chemically in different ways, which weakens them. For example, water can reach with some rocks to break them down, and air can weaken minerals through a process called oxidation.
Biological weathering-
rocks and land can be broken down by actions of living organisms such as plants and animals, for example, rabbits burrowing into river banks.
Mass movement-
when material moves downhill.
Sliding-
where a section of land falls down a slope and dislodges other material on it's way down.
Slumping-
where material at the bottom of the slope moves outward
.
Erosion-
wearing away of materials by a moving force.
Abrasion-
when sediment is thrown against a surface by water and rubs the material to smooth the landforms.
Hydraulic action-
where water forces its way into cracks, which creates weakness in rocks, splitting them apart.
Attrition-
Where pebbles hit each other or landforms, making rocks break and get smaller and rounder.
Solution-
where rocks are dissolved in water
Transport-
the movement of material
.
Traction-
the movement of larger sediment rolling the bottom of the sea or a river.
Saltation-
small pieces of sediment rolling the bottom of the sea or a river.
Suspension-
smaller partials can be suspended in water
Solution-
when minerals dissolve in water.
Deposition-
the laying down of materials that have been transported. Making beaches.
