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

Mass Movement

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
