Current Question (ID: 17888)

Question:

$\text{Soil erosion can be prevented by:}$

Options:

1. $\text{Overgrazing}$
2. $\text{Removal of vegetation}$
3. $\text{Afforestation (Plantation)}$
4. $\text{Increasing bird population}$

Solution:

$\text{Plants often bind the soil together with their root systems, which means they’re able to serve as a protective layer that can help prevent soil erosion.}$ $\text{Soil erosion is the removal of the top layer of the soil due to natural or artificial means. The soil moves from one place and gets settled in another area or place.}$ $\text{It is a type of social degradation which can occur in all types of lands. Removal of a high amount of top layer of soil is very harmful and can have serious effects and can cause a threat to the environment.}$ $\text{Some of the methods to prevent soil erosion are:}$ $\text{- Planting more trees as the roots of the stress and plants hold the soil and do not allow the soil to wither off.}$ $\text{- Using fibres logs to prevent soil from moving or sloping}$ $\text{- Proper drainage system to allow proper flow of water in water collecting systems}$ $\text{- Mulch matting can be done.}$
