First, we have weathering. Weathering is the breaking down of rocks into smaller pieces of rock. There are two types, mechanical and chemical. Mechanical is the physical breaking down, whereas chemical changes the composition of the rock.
Hi! My name is Sam, and I am going to teach you the difference between weathering, erosion, and deposition.
Erosion is next, and very simple too! Erosion is the movement of the weathered pieces. They can be moved by wind, water, gravity, or glaciers can pick them up and move them. Erosion by water is most common.
Last is deposition. Deposition is the depositing of the eroded sediments into a new location. Erosion and deposition are how pointbars and cutbanks form. If sediments in a river do not get deposited, they will be deposited at the mouth of the river, forming a Delta, which is the buildup of sediments at the mouth of a river.
That's all you need to know about Weathering, Erosion, and Deposition. Have a good day!
