Erosion
100
removal of fine sediment by wind
deflation
100
The grinding away of rock by other rock particles carried in water, ice, or wind

100
water held underground in the soil or in pores and crevices in rock.
groundwater

measure of the change in elevation
gradient
200
small, solid pieces of material that come from rocks or living things
sediment
200
thick deposits of fine-grained sediments often found far away from their source
