Erosional Forces Ch. 8
a process that wears away surface materials and moves them from one place to another
when sediments are eroded, they are not lost from Earth they are just relocated
any type of erosion that happens as gravity moves materials downslope
when a mass of materials slips down along a curved surface
occurs when sediments slowly shift their positions downhill
a large mass of ice and snow moving on land under its own weight
pieces of rock are lifted out by the ice
as ice retreats, a jumble of boulders, sand, clay, and silt is left behind. The mixture of different-sized sediments is called till
a big ridge of material piles up that 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 wind blows across loose sediment, removing small particles such as silt and sand
when windblown sediment strikes rock, the surface of the rock gets scraped and worn away
Large deposits of windblown sediments
a mound of sediments drifted by the wind
