exogenic processes
processes that happen outside the earth’s core
weathering
the combined action of all physical and chemical processes that disintegrate and decompose rocks through elements of weather
physical/mechanical weathering
happens when rocks are broken up without change in their chemical composition
kinds of physical weathering
frost wedging, salt crystal growth, abrasion
chemical weathering
happens when rocks disintegrate or create new compounds caused by chemical reactions
biotic/biological weathering
happens when rocks disintegrate caused by living organisms
factors that contribute to weathering
climate, time, typography, rock type, rock structure
erosion
the process that removes rock, soil, and other dissolved materials from one place to another
agents of erosion
running surface water, wind, glaciers, waves
mass wasting
the downslope motion of soil caused by the force of gravity
transportation
the acquisition of rock debris by geomorphic agents like winds, waves, etc
deposition
the process that happens after erosion. this process adds sediments, soil, and rocks to a landform or land mass.
