प्रश्न
Explain how forests prevent floods.
उत्तर
- Forests naturally absorb water. It allows rainwater to leak through. In the absence of trees, rainwater would fall directly on the ground, resulting in flooding.
- However, due to the presence of trees, rainwater does not fall directly to the ground. It strikes the ground gently.
- As a result, before floods, all rainwater sinks into the earth. Forests act as a natural barrier to flooding.
