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

Definitions of...
1- deflaction
The wind detaches and removes loose particles from the surface of the Earth.
2- abrasion
The material transported by the wind ,following the process of deflation,crashes into rocks.The impact and fricition of this material on rocks polishes and wears away at them
Two conditions for erosion
Presence of loose material
Absence of vegetation
Depositional landforms
The term moraine is used to refer to the material that a glacier is carraying as well as the sediment that it has deposited
Moraines
lateral moraines
medial moraines
terminal moraines
Sea
landforms caused by erosion
Natural bridges
Wave-cut platforms
Headlands and bays
2 methods for transport of eroded material
Longshore drift
Waves
Two water movements causing EROSION
Waves
Tides
landforms caused by deposition
Spits
Deltas
Lagoons
