Explanation:
*Erosion is the action of surface processes that removes soil, rock, or dissolved material from one location on the Earth’s crust and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement.
*Soil erosion occurs primarily when dirt is left exposed to strong winds, hard rains, and flowing water. In some cases, human activities, especially farming and land clearing, leave soil vulnerable to erosion.
*The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.
*For areas with light erosion problems, replanting with vegetation and covering with mulch are good solutions. For erosion along footpaths, covering with mulch or stone is the best option. For heavy erosion in areas of concentrated flow, the most effective solutions are check dams or terraces.
Answer:
1. What is Erosion?
Answer:
Erosion is the action of surface processes that removes soil, rock, or dissolved material from one location on the Earth’s crust and then transports it to another location where it is deposited.
2. What are the causes of soil erosion?
Answer:
Soil erosion occurs primarily when dirt is left exposed to strong winds, hard rains, and flowing water. In some cases, human activities, especially farming and land clearing, leave soil vulnerable to erosion.
3. What are the harmful effects of soil erosion?
Answer:
The harmful effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.
4. How can we stop soil erosion?
Answer:
Replanting with vegetation and covering with mulch are good solutions. For erosion along footpaths, covering with mulch or stone is the best option. For heavy erosion in areas of concentrated flow, the most effective solutions are check dams or terraces.
