Answer 1

The correct option is D Both statements are correct.


An increase in the forest cover can help with floods in two ways. It helps in reducing the sudden flooding and also in reducing soil erosion.
The roots of trees slow down the running water allowing it to percolate down.
Soil erosion is a cause of flooding. Vegetation cover over an area reduces soil erosion as roots of the plant hold together the soil.
