Match the following. Column A Column B 1. Leakage of oil a. Cloud 2. Reservoir b. Plant growth 3. Distillation c. Pollute marine organisms 4. Rainwater harvesting d. Influenza virus 5. Swine Flu e. Man-made lake

1-c Oil leakages on the surface of the sea pollute the marine organisms. 2-e Man-made lakes created when dam is built on a river is called reservoir. Small areas filled with water are called ponds. 3-a Clouds form when water vapour in the atmosphere rises and meets cool air. The cool air causes the water to then condense into droplets. The same process of condensation is at work during distillation, which is essentially when a liquid is purified through temperature changes. 4-b Rain water harvesting can improve plant growth. It can reduce top soil loss and ground water level can be increased. 5-d Swine flu is a respiratory disease caused by Influenza virus that infects the respiratory tracts of pigs and results in barking cough.

Man-made lakes created when a dam is built on a river is called a reservoir. Note: Reservoirs are great because they provide a supply of water for when naturally occurring bodies of water, like lakes or rivers, run dry.
