Conservation of Water Resources — Flashcards

Answer

Rain water harvesting means collecting rainwater during the rainy season in large tanks, cisterns, reservoirs, or other suitable systems for future use. It is a method of conserving water resources.

Answer

Rainwater recharges ground water and helps maintain river flow. When rainwater is collected and stored instead of being wasted, it supports water availability for later use.

Answer

Most rainwater causes floods or flows away. If it is not collected or used properly, a precious natural resource is lost.

Answer

Increasing population puts pressure on ground water levels because more water is needed for homes, schools, industries, and other uses. This increases the demand on available water resources.

Answer

In urban areas, rainwater can be used to recharge ground water because many surfaces do not allow water to soak into the ground easily. Conserving rainwater helps protect ground water levels in cities…

Answer

There are different ways of harvesting rainwater. It can be collected in tanks, cisterns, and reservoirs, and it can also be used to recharge ground water through suitable methods such as soak pits.

Answer

Soak pits are a method used to improve ground water levels. They help rainwater soak into the ground, which supports ground water recharge.

Answer

Cementing house surroundings prevents water from percolating into the ground. Because of this, rainwater flows away instead of recharging ground water.
