Commision. cannot be held responsible for any use which may be of the information contained therein.. Anticipated Problem: . What is soil erosion?. I. . Soil erosion . is the process by which soil is moved. When soil is eroded, it may become pollution in the water or air. The land where it came from, loses fertility. Vegetation and other coverings help prevent soil erosion. . * 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. Chad Lentz. Why Care?. Removes valuable topsoil. Carries away expensive nutrients. Increase tillage costs to fix. Creates algae blooms and dead zones due to excess nutrients in waterways. Types of Erosion. Nancy . Rogel. Eddie . Guadarrama. . Outline. What is Soil Erosion. Types of Erosion. Factors Affecting Erosion Rates. Human Activities that increase Erosion Rates. How to Prevent Erosion. What is Soil Erosion. Lesson 1. Water Erosion. How does Moving Water Cause Erosion?. Erosion is the process in which sediment that has been broken down through weathering is moved.. Agents of Erosion are:. Water. Wind. Glacial (ice). 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.. . (“Flow-Assisted”. . or “Flow-Accelerated”. . Corrosion). An increase in corrosion brought about by a high relative velocity between the corrosive environment and the surface.. Removal of the metal may be:. Runoff meander Rill oxbow lake turbulence. Gully alluvial fan ice age. Stream delta River. groundwater Tributary sand dune. Drainage basin Divide abrasion Flood plain beach. deflation. - running water is the most effective agent of erosion. - gravity draws surface water downhill, which allows the water to erode soil and rock materials. - rivers also eventually leave their eroded materials behind, which we refer to as . 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 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. DSE3T : Factor, Processes and Mitigation Soil Erosion Soil is the most precious gift of nature - Prime resource - for food, fodder etc. for food, fodder etc. It is the earth’s fragile covering t
