Answer 2

Answer:

➀ Soil is the thin layer of material covering the earth's surface and is formed from the weathering of rocks.

➁Soil erosion is the displacement of the upper layer of soil; it is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice, snow, air, plants, animals, and humans.

➂The various methods for preventing and reducing soil erosion are:

• Preventing excessive grazing
• Prevention of deforestation
• Plantation of trees and plants
• Mulch matting can be used to reduce erosion on the slopes
• Put a series of fibre logs to prevent any water or soil from washing away

Explanation:

• Pedogenesis

The soil formation process is termed 'pedogenesis'. Climatic conditions are important factors affecting both the form and rate of physical and chemical weathering of the parent material.
