is a process that wears away surface materials and moves them from one place to another.
Deposition
agents of erosion drop by sediments they are carrying as they lose energy.
Mass movement
is any type of erosion that happens as gravity moves materials downslope.
Slump
when a mass of material slips down along a curved surface, the mass movement is called slump.
Creep
occurs when sediments slowly shift their position downhill.
a large mass of ice and snnow moving on land under its own weight.
Plucking
glaciers weather and erode, then when glacial ice melts, water flows into the cracks in rocks, later the water refreezes in these cracks, expands, and fractures the rock, finally pieces of rocks are lifted out by the ice.
Till
mixture of jumbled boulders, sand, clay, and silt.
Moraine
a big ridge of material that looks like it has been moved by a bulldozer.
Outwash
when glacial ice starts to melt, the melt water can deposit sediment that is diferent from till.
Deflation
wind blows across loose sediments removing small particles such as silt and sand.
Abrasion
when windblown sediments strikes rock, the surface began scrapping and worn away.
Loess
windblown deposit of tightly packed, fine-grained sediments.
Dunes
mound formed when windblown sediments pile up behind an obstacle.
