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 . * Earth’s main agent of natural erosion. What is erosion?. Erosion is. -. Agents of Erosion. Agents of erosion include. . --. Running water . is the. . big. . Kahuna. . of. . all. . erosional. Weathering. The breakdown do the materials of Earth’s crust into smaller pieces.. Physical Weathering. Process by which rocks are broken down into smaller pieces by external conditions.. Types of Physical weathering. Chapter 7. Section 7.1 Weathering. Weathering is the process by which rocks on or near Earth’s surface break down and change. . Erosion is the removal and transport of weathered material from one location to another.. The . surface. features of the Earth change as a result of observable physical and chemical processes . Weathering and Erosion. This is a monument . called Cleopatra’s . Needle. It was carved in Egypt around 1450B.C. The sides are carved with hieroglyphs, the writing of ancient Egypt. It stood in the dry, hot Egyptian desert for over 3000 years. During that time, the hieroglyphs remained distinct.. 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. Learning objectives. To be able to . define. the . five . processes of . marine coastal . erosion. .. To be able to . explain. the . factors. . affecting coastal erosion.. To describe . the difference between concordant and discordant . another.. 2 . kinds:. 1) . Rill erosion. is the erosion by running water in small channels. , on the side of a slope.. 2) . Gully erosion. is when a rill channel evolves to become deep and wide.. WHAT IS COASTAL EROSION? Coastal erosion is the endless reshaping of shorelines by waves, currents, tides, storms, ice, rain and groundwater seepage. Human activities, like construction, dredging, CO CONTROL LEAD. TRAINING.
