Geography- Physical 2.a. Climatic & Geomorphic Processes

... is the process of physcially or chemically altering materials from surface rock

Weathering

1 of 16

Weathering: ... weathering is mainly the breakdown of rocks without chemical change. main types of ... weathering are Freeze-Thaw, Salt Crystallisation and Wetting and Drying

Physical

2 of 16

Weathering: ... weathering involves a ... reaction, a deposit is usually made which can be easily eroded. This can happen in many ways including Carbondation, Oxidation and Solution

Chemical

3 of 16

Weathering; ... weathering is organic activity breaking up rocks, including Roots, water, Birds, Marine Creatures and animals

BIological

... is activity on a downward slope by gravity. It can be slow or fast depending on the forces and other affecting factors. The main processes are Rockfall and Slides, and have some minor processes including Soil Creep, Mud Flows, Landslides, Runoff

Mass Movement

5 of 16

Mass Movement: ...usually occur whene there is a fault between layers of rock

Slides

6 of 16

Mass Movement: ... is when rock breaks off cliffs because of Physical Weathering

Rockfall

7 of 16

... influence geomorphic processes because they are the driving force for erosion, transportation and deposition

Waves

8 of 16

... processes occur at river mouths and in low energy- estuarine environments

Fluvial

9 of 16

Fluvial Processes: Fluvial ... is very similar to the waves with how it ... rock, but in this case it happens in rivers

Erosion

10 of 16

Fluvial Processes: Fluvial ... is also similiar to the ... by waves where sediment is moved

Transportation

11 of 16

Fluvial Processes: Fluvial ... occurs because rivers lose their velocity at the river mouth and have to drop the sediment being carried

Deposition

12 of 16

... processes occur in the air, and usually coastal landscpaes are significantly influenced by wind. Their processes also include erosion, transportation and deposition

Aeolian

13 of 16

Aeolian Processes: Aeolian ... picks up sediment and due to the wind speed, the ... rates are increased more than usual ...

Erosion

14 of 16

Aeolian Processes: Aeolian ... is moving sediment in the air, using the same concepts as ... in water, sediments of all different sizes are moved if the energy is right

Transportation

15 of 16

Aeolian Processes: Aeolian ... is when material is carried by the wind and then ... when the wind speed falls and energy is lost. Usually surface friction is the reason for wind spped falling
