What term describes a long period of no water?

• A. Drought
• B. Flood
• C. Rainstorm
• D. Desertification

Answer: (A)

A long period with little or no water is called a drought. Drought describes a sustained deficiency in water supply relative to normal conditions, often lasting months to years and affecting rainfall, river flows, reservoir levels, soil moisture, and agriculture. It isn’t about a single weather event but rather a prolonged shortage that can have widespread impacts on drinking water, crops, and ecosystems.

Why this fits best: drought specifically captures the idea of a persistent water shortage, not just a momentary event. A flood is the opposite—too much water in a short time. A rainstorm is a brief heavy rainfall event, not a prolonged shortage. Desertification involves land degradation toward arid conditions, which can be driven by drought but is a longer-term process of ecosystem change rather than the immediate lack of water itself.
