Gravity erosion

Land slides

1. Gravity Erosion

2. Gravity Erosion Gravity erosion defined as the transfer of rock and soil down slope by indirect or direct action of gravity with or without a flowing medium (such as water or ice). Some of the best examples are : Slump Creep Rockfalls Rock slides Mud flows Ava;anches

3. Gravity Erosion

4. Slump Occurs when a mass of material slips down along a curved surface's leaves a curved scar where the slumped material originated. The slope becomes so steep that the base material cannot support the material above it. The base material is weaker than the material above it (ex. clay)Water moves to the base of a slipping mass of sediment.

5. Causes structures and trees to “lean” uphill.

6. Humans are constantly influencing the nature of our landscapes. HOUSES, ROADS, BUILDINGS, DEVELOPMENTS, CANALS, etc., all change the shape and appearance of the land .

8. Landslides/ Rockslide A  landslide  happens when a large amount of soil and rock suddenly falls down a slope because of gravity.

9. Rockslide Occur when layers of rock slip downslope suddenly. Commonly occur on steep slopes in mountainous areas or areas with steep cliffs. Happen most often after heavy rains or earthquakes.

11. Mud Flow Occur when heavy rains mix with sediment causing the sediment to become thick and pasty and then move downhill under the force of gravity. The materials of the mudflow are deposited at the base of the slope…often in a fan shape. Usually occur in areas that have thick layers of loose sediments. Often happen after vegetation has been removed by fire.
