Answer 2

'SOIL EROSION'

Explanation:

• 'Soil erosion' is elucidated as the gradual process of removal or displacement of the top layer of the soil along with its nutrients.
• The erosion of the upper layer of the soil is primarily caused by natural as well as man-made factors.
• The natural factors include: wind(cyclones), water(Tsunamis, hurricanes, etc.), fire(volcanic eruptions, forest fires, etc.).
• The man-made factors include excessive cultivation, overgrazing, deforestation, etc.
• Soil erosion badly affects the fertility of the land and crop yields.
• It causes increased pollution in rivers and streams and worsen the situation of flooding, etc.
• Thus, it needs to be prevented which can be done through various methods like afforestation, construction of dams, contour farming, etc. that would help protect the top layer of the soil and retain its nutritive ability to promote good yields.
