Weathering, Erosion, and Deposition by Zachary Reuss https://padlet.com/zachary_reuss/az99z95u3d1x Made by Zach Reuss period 4 en-us 2018-03-20 15:09:18 UTC 2024-05-03 11:43:48 UTC hello@padlet.com Weathering is the breaking down of rock into sediment. There are two types of Weathering. These two types include Mechanical and Chemical. Mechanical Weathering is: The process of breaking down rocks, this is usually caused by temperature changes. An example of Mechanical Weathering is water sometimes gets into tiny cracks and if that water freezes, it expands, opening the crack even more and eventually splitting the rock into pieces. There is also Chemical Weathering, which is: The erosion of rocks (breaking down) caused by chemical reactions, acid rain, oxidation, acid from organisms. An example of Chemical Weathering is carbonation. Carbonation is the mixing of water with carbon dioxide to make carbonic acid. Chemical Weathering is important in the forming caves. zachary_reuss https://padlet.com/zachary_reuss/az99z95u3d1x/wish/244074409 2018-03-20 15:13:59 UTC https://padlet.com/zachary_reuss/az99z95u3d1x/wish/244074409 Erosion is the process by which sediment and other materials are moved from one place to another. It directly effects the shape of structures. A few examples of Erosion are Canyons, Gorges and V-Shaped valleys. The Grand Canyon is an example of Erosion, because the water that is flowing downhill of the rock can steadily wear away at it which is how the Grand Canyon and other canyons form due to Erosion. Although roots do help to prevent erosion, because the plants help keep land intact. Plants slow down water flow and the roots help hold the soil in place. Erosion also erodes rocks into V-shaped rivers. The reason for this is, V-Shaped valleys (also known as a river valley) the exact shape depends on the stream flowing through it. Steep gradients will make steep walls and a narrow bottom. zachary_reuss https://padlet.com/zachary_reuss/az99z95u3d1x/wish/244082757 2018-03-20 15:26:02 UTC https://padlet.com/zachary_reuss/az99z95u3d1x/wish/244082757 Deposition is the process in which eroded materoids are dropped-dumping sediment , dirt, rocks or particles in one place. Although gravity must be greater than the force of the stream. Examples are Deltas, Dunes, Beaches, Flood Plains. A dune is: A mound or ridge of sand or other loose sediment. Mounds of sand shape are deposited by wind. A dune forms because of deposited sediment and rocks. Deposition is also the gas to solid phase and can form multiple arrays of things including the examples I explained above. zachary_reuss https://padlet.com/zachary_reuss/az99z95u3d1x/wish/244165410 2018-03-20 17:24:15 UTC https://padlet.com/zachary_reuss/az99z95u3d1x/wish/244165410
