Erosion
• Erosion is the wearing away of an object or substance
through an external force.
• Typically, erosion refers to the gradual wearing away
of soil, dirt, rock, or other land structures over time
through natural forces such as water or wind.
• Humans have contributed to erosion in negative ways.
• Deforestation, in which trees are cleared to make
room for development. The soil is easily eroded by
wind and water

Soil erosion occurs due to,
1. Water
2. Wind
3. Ice
4. Gravitational forces
a. Raindrop splash erosion:
• Raindrops fall with a speed of over 9 m per second.
• When raindrops hit bare soil with this speed, they beat it into flowing
mud. The splashes reach more than 60 cm high and 150 cm away.
• However, if soil is covered with plants, raindrops do not hit the ground
with the same speed.
