Erosion Land Forms. Moving water causes erosion. The force of water hitting the ground can loosen materials. Moving water carries particles with it. Runoff. Moving water across land. Rills and Gullies. Rill- small groove formed by moving water Gully- larger groove; formed by moving water
Land Degradation & Soil Erosion. Introduction Land degradation Soil Erosion Water Erosion Wind Erosion Soil Conservation. Land Degradation. This is the reduction of the productive potential of lands for human use. Land degradation is caused by such phenomena as:
Riparian/Land Use/Bank Erosion. Riparian Width. Riparian vegetation includes trees, shrubs and wetlands; not grasses Select one width or two and average for each bank, then average banks together. Woody Riparian Quality.
Lesson 12 - Land Slope and Erosion. Slope - the degree of change in elevation over a length of land a. water and slope * steeper the hill = more slope = more erosion * flatter the land = less slope = less erosion b. wind and slope * steeper slope = bare land = more wind erosion
EROSION. WHAT IS EROSION?. During erosion, soil or rocks are carried away to a new place by moving water. What are the natural things that causes erosion?. Moving water takes soil and rocks to other places The water also rubs on the rocks and makes them smooth
Erosion. Yg Erosion Team Carson. The problem. There are area’s at our school that show evidence about water erosion. This is a power point about the problem . Our principal has asked us to investigate. All four of us are making power points. This is Carson’s power point. Area’s.
Erosion. Jodi Knoebel. Topics of Discussion. Mass movements Running water Glaciers wind. Mass Movements. Caused from gravity Occur on steep slopes Increase with rain flow. Slump. Steep slopes Material underneath has weakened. Creep.
Erosion. • outline a cause of soil erosion in NSW due to: – an agricultural process – urbanisation and identify a management strategy that prevents or reduces both of these causes of soil erosion (2.2.1)
Erosion. Erosion is the movement of soil particles from one place to another by water or wind. Water Erosion: Erosion by water is caused by raindrops, surface flow, and gully flow. Wind Erosion:
