Erosion and Deposition essays

Erosion and Deposition essays Erosion and deposition, two actions that shape the world. Without them, earths landscaping would be similar to mars. Erosion is often confused with weathering, people believe that erosion is the act of breaking down sediments when in fact it is a mode of transportation for these broken down sediments. Such modes of transportation are; running water, glacial movement, and wind. Erosion by definition is, the process by which earth materials are moved by natural agents like moving water, wind and ice. Deposition is the depositing of theses sediments in certain areas. for example wind deposits sand on any object where it continues to be deposited and forms a sand dune a large deposit if sand. erosion and deposition happens in many ways in forms and in many places. Running water is the most effective agent of erosion on the earth. running water includes all water that falls on earth and moves down hill under the pull of gravity, be it rain, snow or any other form of precipitation. like other agents of erosion, waters energy comes from the sun. The sun lifts water by evaporation and eventually it is redeposited all over the world. A key word to running water is carrying power. the carrying power of any source of running water is indicated by the amount and size of the sediment in the water. some other key words are, slope, and velocity. The greater the slope of the bed of a stream, the greater the velocity (or speed) the water will have, then the greater the carrying power and in turn the greater the erosion. running water erodes surfaces by a force called abrasion. Running water breaks up its bedrock by a grinding action called abrasion. the body of water will use the sediments its carrying, (pebbles, sand, gravel, boulders), as cutting tools to wear away at anything in its path. A river will roar straight down a mountain carrying anything in its path because the mountain is on a slope, the...
