Question

8. Define soil erosion and its types. Write the causes of soil erosion in hilly, desert and the plains. Also suggest solutions for the same.
9. Define Sustainable Development. Explain its importance in two points.

Answer 1

Answer:

Soil erosion is defined as the wearing away of topsoil. Topsoil is the top layer of soil and is the most fertile because it contains the most organic, nutrient-rich materials. Therefore, this is the layer that farmers want to protect for growing their crops and ranchers want to protect for growing grasses for their cattle to graze on.

Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.

Sustainable development has continued to evolve as that of protecting the world’s resources while its true agenda is to control the world’s resources. Environmentally sustainable economic growth refers to economic development that meets the needs of all without leaving future generations with fewer natural resources than those we enjoy today.
