PPT-Erosion & Mass Movement

erosion is the process by which the products of weathering are transported agents of erosion are gravity wind glaciers water ocean waves currents streams groundwater What is erosion What is Soil Erosion. Weathering and Erosion. Shaping the Earth’s Crust. The rocks and soil of the earth’s crust are continually being worn down because of a number of processes.. These processes are known collectively as . Rain . Splash. Sheet. Rill. Gully . Heavy . rains in northwest Iowa washed away soil, leaving this scarred tableau. This type of erosion, termed sheet-and-rill erosion, occurs when there is insufficient vegetation to hold soil in place. As rain falls, it forms sheets of surface water that transport soil away. As more water accumulates, it forms runoff channels called rills, which further displace soil.. Agents. of Weathering and Erosion. Gravity not only influences. the movement of water and ice but also causes rocks and soil to move downslope.. Mass Movement: the movement of any material, such as rock, soil, or snow, downslope. Denudation Processes. Means do what's on the slide. Means read the slide. While volcanic activity in . TVC . leads mainly to building up the mountains, the weathering-erosion-transport-deposition system is trying to level them down. Isostatic sea level change can be attributed to the wait of ice. And is a local change because the ice only covers a local area. . Eustatic . YOU STATIC change – caused by you as you cause global warming which cause ice cap melt which adds water to the see.. Weathering. Weathering is the process that breaks down rock and other substances at the Earth’s surface. . Heat, cold, water, and ice all contribute to weathering.. Repeated freezing and thawing for example can crack rock apart into smaller pieces. . Earth’s land is made of slope and as the force of gravity works on the slope materials move downslope. . This movement is called mass movement. Weathering and mass movement produce most landforms.. 1. Mass Movement. A down . slope movement of loose sediment and weathered rocks resulting from the force of gravity..  Erosion following weathering climatic conditions determine which materials and how much.

THK JAIN COLLEGE. WHAT IS SOIL EROSION. . Soil erosion is a type of soil degradation in which there is wearing away or displacement of the upper layer of soil (topsoil).. Soil erosion is a global threat in the current world scenario.. The creation of sedimentary rocks. Weathering and Mass Movement. Objectives:. 1. Describe the processes by which erosion wears down and carries away rock. 2. Distinguish between chemical and mechanical weathering. Tuesday, 10 September 2019. How do geomorphic processes shape the land?. Starter. Practice exam question. . Geomorphic Processes. What does the term . ‘geomorphic processes’ . mean?. A . geomorphic process . Coastal . Landscapes - KO. Terms. Deposition. The laying down of material at the. coast.. Erosion. The wearing. away of material at the coast.. Hard engineering. Man-made structures. to protect the coast from erosion.. Section 4:. Erosion. Erosion. – transporting weathered material, agents – gravity, wind, glacier, & water. Soil erosion major concern. Soil erodes faster than its made. Land use & climate affect S.E..
