loose materials such as rock fragments, minerals grains, and bits of shell that have been moved by win, water, ice or gravity

form when sediments are pressed and cemented together or when minerals form from solutions

occurs when water soaks through soil and rock

layers upon layers of sediments build up and pressure from upper layers compact lower layers.

detrital, organic, chemical

means to wear away, they are made from the broken fragments of other rocks, then compacted and cemented together to form solid rock.

rocks that are made from once living things

form when dissolved minerals come out of solution.Like when salt is left at the bottom of the pan when the solution is dissolved from the pan

Mechanical breaks and wears away pieces and chips of materials while chemical reactions change the material into a different material

gravity, water, wind, glacier

slump - when a mass of material slips down a long a curved surface

creep - when sediments slowly shift their positions downhill

rockfalls and rock slides - when layers of rock slip downhill suddenly

mudflows - a thick mixture of sediments and water flowing down a hill

plucking - boulders, gravel and sand being added to the bottom and sides of a glacier

moraine deposits

a ridge of material and looks as though it has been pushed along by a bulldozer

material deposited by the meltwater from a glacier, most often beyond the end of the glacier

when the glacier melts, a winding ridge of sand and gravel is left behind

deflation - it blows across loose sediment, removing small particles such as silt and sand

abrasion - sandblasting; workers use machines that spray a mixture of sand and water under high pressure against a building; wearing it away making it look like an odd rock

dust storms
sandstorms

rill and gully - when water creates a channel way on soil making rill and when it gets deeper it is a gully

sheet erosion - when water slowly moves down a hill in layers, like water on a car hood

stream erosion - when a stream gets wider when the water carries the sediments from the side of the channel, widening it

the larger the grain size, the steeper the slope

erosion is the moving while weathering is the breaking off
