Question

Rainwater that falls on the roof of houses can be effectively conserved by using:

• A. Earth Dams
• B. Drip Irrigation
• C. Rainwater Harvesting
• D. Sprinklers

Answer 1

Answer:

C. Rainwater Harvesting

Rainwater Harvesting

• Rainwater harvesting is the specific practice of collecting and storing rainwater for future use, rather than letting it run off. When done on the roof of a house, it is often called Rooftop Rainwater Harvesting.

• The Process: Rain falls on the roof (the catchment area), travels through gutters and pipes (conduits), passes through a filter to remove debris, and is finally stored in a tank or used to recharge groundwater.

• The Benefit: It provides a self-reliant water source for gardening, toilets, or even drinking (if treated), especially in areas with water scarcity.

• Earth Dams : These are large structures built across a river or stream to collect water on a massive scale.

• Drip Irrigation : This is a water-saving method for farming where water is delivered directly to the roots of plants drop by drop. It uses water efficiently but isn't a method for collecting rain.

• Sprinklers : These are tools used to spray water over a large area (like a lawn). Like drip irrigation, this is a way to spend water, not conserve or collect it from the clouds.
