Recap! What is soil Erosion?
What are the 4 main causes of soil erosion?
• Overgrazing – too many animals eat all the grass
• Up and Down Ploughing – Water runs down the furrows
• Deforestation – trees provide protection and hold the soil together
• Soil exhaustion – soils are over-used and can grow no more

Lets read the second Paragraph on Page 34

What causes soil erosion in Nepal?
Melting snow
Unstable soil
Heavy Rain
Steep Slopes
Population IncreaseTourists & Trekkers
Trees for firewood
Increase in animal numbers
Physical Factors or Human Factors
Terraces collapse

How do these create erosion?
Melting snow
Unstable soil
Heavy Rain
Steep Slopes
Population Increase
Tourists & Trekkers Trees for firewood
Increase in animal numbers
Soils need to be stabilised - Terraces
Deforestation
Overgrazing
Terraces under threat and some collapse
