Question

which of the following best explains why deforestation increases the risk of floods in an area? a. tree leaves catch and retain rain water. b. trees block the free flow of water. c. deforestation increases precipitation. d. tree roots improve soil water retention. please select the best answer from the choices provided

Explanation:

Tree roots bind soil particles together and create channels that allow water to infiltrate the soil, improving its water - holding capacity. When deforestation occurs, these roots are removed, reducing soil water retention and increasing surface runoff, which can lead to floods. Tree leaves catching rain water is a minor factor compared to root - related soil water retention. Trees do not block the free flow of water in a way that would prevent floods; rather, their absence leads to problems. Deforestation generally does not increase precipitation.

Answer:

D. Tree roots improve soil water retention.
