The method of bringing water to dry areas

The method of bringing water to dry areas

• A. Irrigation
• B. Desalination
• C. Evaporation
• D. Hydroponics

Answer: (A)

The idea being tested is how people supply water to crops in places where rainfall is insufficient. The method that fits this hydraulic need best is irrigation—the deliberate delivery of water to fields through canals, pumps, sprinklers, or drip systems. By moving water from rivers, reservoirs, or aquifers to dry areas, irrigation makes agriculture possible in arid regions and allows farmers to control when and how much water crops receive, which helps maximize yields and conserve supplies with efficient techniques like drip irrigation. Desalination produces freshwater from seawater, but it’s about making usable water rather than the act of bringing water to fields. Evaporation is the natural process of water turning into vapor, not a method for delivering water to crops. Hydroponics involves growing plants in a nutrient solution, which uses water efficiently but is a farming method rather than a general way of bringing water to dry land.
