What term describes the collection and use of rainwater from rooftops?

• A. Recharge
• B. Rainwater harvesting
• C. Store
• D. Sediment

Answer: (B)

Collecting rainwater from a roof and using it later is rainwater harvesting. This term covers both capturing the rainfall through gutters and downpipes and then storing or using that water, for example in tanks for irrigation, toilets, or washing. Recharge refers to letting rainwater seep to replenish groundwater, which is a different idea from storing and using captured rainwater. Sediment is about particles carried by water, not the practice of collecting and using rainwater. The clear fit here is rainwater harvesting because it describes both the collection from rooftops and its subsequent use.
