Which term describes the process of collecting and storing water for later use?

• A. Remote sensing
• B. Reservoir
• C. Quadrat
• D. Rainwater harvesting

Answer: (D)

Rainwater harvesting is the process of catching rain and storing it for later use. It typically uses roof catchments, gutters, and downpipes that channel water into storage tanks or barrels. Stored water can then be used for irrigation, flushing toilets, or even treated for drinking in some setups, making it a sustainable way to supplement mains water and reduce runoff. The other terms don’t fit: remote sensing is about observing the Earth from a distance, a reservoir is a storage place rather than the act of collecting, and a quadrat is a sampling method used to study populations.
