EXTERNAL GEOLOGICAL PROCESSES
WIND
Erosional landforms
Honeycombs
Desert pavement
Mushroom rocks
Definition of...
1- Deflaction
The wind detaches and removes loose particles from the surface of the Earth in a process called deflation
2- Abrasion
The matirial transported by the wind, folllowing the process of deflation, crashes into rocks. The impact and friction of this material on rocks polishes and wears away at them.
Two conditions for erosion
Absence of vegetation
Presence of loose material
Depositional landforms
Dune
Loess
SEA
Two water movements causing EROSION
Tides
Waves
Landforms caused by erosion
Wave-cut platforms
Cliffs
Natural bridges
Seastacks
Headlands and bays
Landforms caused by deposition
Deltas
Tombolos
Splits
Marshes
Lagoons
Beaches
Sandbars
2 methods for transport eroded material
Waves
Longshore drift

Definition of
Glacier
Is a thick mass of ice that moves over land
Iceberg
Is a large piece of ice that has broken off a glacier and fallen into a lake or the sea.
