Question

Which of the following should be increased to prevent soil erosion?

• A. Flow of water
• B. Green areas
• C. Deforestation
• D. None of these

Answer 1

The correct option is B Green areas

Trees keep the soil particles bound together. They have roots that extend deep in the soil. The roots of trees hold the soil particles tightly together and prevent their erosion and washing away due to factors like wind, water, rains etc.

So, option B is the correct answer.
