Soil erosion is a naturally occurring process that affects all landforms and can occur slowly over time or rapidly, causing serious topsoil loss. There are four main types of erosion: sheet erosion, gully erosion, channel erosion, and rill erosion. Soil erosion is caused by both natural processes like wind and water flowing downhill, as well as human activities such as overcropping, deforestation, and overgrazing. Problems from soil erosion include loss of topsoil, damage to fields, decreased plant productivity, and desertification. Remedies include avoiding overgrazing, conserving wetlands, terracing, and encouraging water infiltration.

2. • Soil erosion is one form of soil degradation
• Soil erosion is a naturally occurring process
that affect all land forms
• It may be slow process that continues
relatively unnoticed or can occurring at an
alarming rate causing serious loss of topsoil

3. TYPES OF EROSION
 SHEET EROSION
 GULLY EROSION
 CHANNEL EROSION
 RILL EROSION

4. SHEET EROSION
The removal of a uniform layer of soil from
the surface by runoff
GULLY EROSION
The accumulation of water in narrow cuts which
removes the soil to considerable deapth.
These cuts can be several feet deep.

5. CHANNEL EROSION
The scouring of stream banks by increased water flows
DRILL EROSION
The process where numerous small cuts are formed

6. CAUSES
Natural process
Wind
Water flowing down

7. Human activities
Over cropping
Deforestation
Over stocking
 overgraing

8. PROBLEMS
Loss of valuable topsoil
Damage to fields
Dicrease in plan productivity
desertification

9. REMEDIES
Avoid overgrazing
Conserve wetlands
Terracing can also be affective
Large steps cut in to a hillside
Encourage water infiltrationdicrease in plant
 productivity
