Geomorphic Processes

For the 9-1 Geography A course

Weathering
is the breakdown of material in the place they were found by mechanical, chemical and biological processes
1 of 18
Mechanical Weathering
he physical actions of rain, frost and wind that create weaknesses in rocks.
2 of 18
Chemical Weathering
minerals can react chemically in different ways, which weakens them. For example, water can react with some rocks to break them down, and air can weaken minerals through a process called oxidisation.
3 of 18
Biological Weathering
rocks and land can be broken down by the actions of living organisms such as plants and animals, for example, rabbits burrowing into river banks.
4 of 18
Mass Movement
Movement of substance downhill due to gravity.
5 of 18
Sliding
Material falls down the slope and disloges other material on the way.
6 of 18
Slumping
Material at the bottom moves outwards, resulting in the slumping of material above.
7 of 18
Erosion
Wearing away of materials by a moving force- river, waes, ice, wind.
8 of 18
Abrasian
Sediment is thrown against the surface to rub and smooth the landform.
9 of 18
Hydraulic Action
Water enters cracks and makes the rocks weaker, splitting them apart.
10 of 18
Attiriton
Pebbles hit each other/landforms making rocks break and get smaller and rounder
11 of 18
Solution
Rocks are dissolved in water.
12 of 18
Transport
Movement of material along the coast by waves/along a riverbed by the river.
13 of 18
Traction
Movement of larger sediment rolling along the bottom of the sea/river
14 of 18
Saltation
Small pieces of sediment picked up temporarily in the water
15 of 18
Suspension
Smaller particles suspended in water
16 of 18
Solution
Minerals dissolve in water.
17 of 18
Deposition
Laying down of transported materials- creating new landforms such as beaches/spits/tombolos.
