Question

1. what is the purpose of rainwater harvesting?

a. to reduce soil erosion
b. to collect and store rain for later use
c. to increase stormwater runoff
d. to filter ocean water for irrigation

Explanation:

Rainwater harvesting is the process of collecting and storing rainwater for future use (e.g., irrigation, domestic use). Option a: reducing soil erosion is not the main purpose of rainwater harvesting (though some methods might have a minor effect, it's not the primary goal). Option c: increasing stormwater runoff is opposite to what rainwater harvesting aims (it reduces runoff by capturing rain). Option d: rainwater harvesting doesn't involve filtering ocean water (it's about rain, not ocean water). So the correct option is b.

Answer:

b. To collect and store rain for later use
