Weathering, Erosion, and Deposition Exam Q’s and
A’s | A+ Graded
weathering - -The chemical and physical processes that break down rock at Earth's
surface.
-erosion - -The process by which water, ice, wind,or gravity moves weathered rock or soil.
-uniformitarianism - -The geologic principle that the same geologic processes that operate
today operated in the past to change Earth's surface.
-mechanical weathering - -The type of weathering in which rock is physically broken into
smaller pieces.
-abrasion - -The grinding away of rock by other rock particles carried in water, ice, or
wind.
-ice wedging - -The process that splits rock when water seeps into cracks, then freezes and
expands.
-chemical weathering - -The process that breaks down rock through chemical changes.
-oxidation - -A chemical change in which a substance combines with oxygen, as when iron
forms rust.
-permeable - -The characteristic of a material full of tiny, connected air spaces that water
can seep through.
-sediment - -Small, solid pieces of material from rocks or organisms; earth materials
deposited by erosion.
-deposition - -The process in which sediment is laid down in new locations.
-gravity - -A force that moves rocks and other materials downhill; the force that pulls
objects towards each other.
-mass movement - -Any one of the several processes by which gravity moves sediment
downhill.
-runoff - -The water that flows over the ground surface rather than soaking into the
ground.
-rill - -A tiny groove in the soil made by flowing water.
