sediment
loose materials such as rock fragments, minerals grains, and bits of shell that have been moved by win, water, ice or gravity
sedimentary rocks
form when sediments are pressed and cemented together or when minerals form from solutions
cementation
occurs when water soaks through soil and rock
compaction
layers upon layers of sediments build up and pressure from upper layers compact lower layers.
What are the major classifications of sedimentary rocks
detrital, organic, chemical
Detrital
means to wear away, they are made from the broken fragments of other rocks, then compacted and cemented together to form solid rock.
organic
rocks that are made from once living things
chemical
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 Weathering vs. Chemical Weathering (Explain, what each is)
Mechanical breaks and wears away pieces and chips of materials while chemical reactions change the material into a different material
what are the agents of erosion
gravity, water, wind, glacier
what does gravity erosion cause (4) and what are they
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
what do glacial erosion cause (1)
plucking - boulders, gravel and sand being added to the bottom and sides of a glacier

moraine deposits
moraine deposits
a ridge of material and looks as though it has been pushed along by a bulldozer
outwash deposits
material deposited by the meltwater from a glacier, most often beyond the end of the glacier
eskers
when the glacier melts, a winding ridge of sand and gravel is left behind
what is caused by wind erosion (5) explain
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
water erosion (3)
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
What determines the slope of the beach?
the larger the grain size, the steeper the slope
diff between weathering and erosion
erosion is the moving while weathering is the breaking off
