Catch water where it falls” is the basic idea behind (a) recycling of water (b) making dams to store water (c) rainwater harvesting condensation of water vapour.
(c): rainwater harvesting Rainwater harvesting is a method used to collect rainwater. By storing the water, we can increase the availability of water which is collected and stored for later use.

1. Floods causes extensive damage to (a) crops (b) property and human life (c) domestic animals all of the above
Solution: (d): all of the above Due to heavy rains, water level rises in rivers, lakes and ponds. This water then spreads over large area causing floods. In turn crop fields, forests, villages and cities get submerged under water. Hence, flood causes extensive damage to crops, domestic animals, property and human life.

Wells are fed by (a) pond water (b) lake water (c) rain water groundwater
(d): groundwater Lakes, ponds, rivers and other water bodies are filled up by rainwater. Some of the rainwater is evaporated back to air. The rest, soil absorbs the water into the ground and becomes available as groundwater. Hence, wells are fed by this ground water.

1. Clouds are (a) tiny drops of water floating in air (b) mixture of dust and water vapour (c) particles of water vapour (d) rain drops in air.
Solution: : tiny drops of water floating in air Water vapour present in air condenses to form tiny droplets of water floating in air which appear to us as clouds. Later these tiny water droplets are formed into larger sized water drops and then get converted to rainfall.

Transpiration is a process in which plants (a) receive water from soil (b) absorb water vapour from air (c) prepare food from water release water vapour
Solution: (d): release water vapour Transpiration is a process when the water is lost in the form of vapour which when parts of a plant (mainly leaves) are exposed is termed as transpiration. The loss of water due to transpiration is quite high.

In which of the following case evaporation of water will be slowest? (a) A tray of water kept in sunlight. (b) A kettle of water kept on a burner. (c) A glass of water kept in a room. (d) A bucket of water kept on rooftop.
(c): A glass of water kept in a room. Evaporation is directly proportional to temperature when temperature increases, evaporation also increases. Temperature in the room will be lower as compared to the temperatures of sunlight, burner and rooftop. So, a glass of water kept in a room has slowest water evaporation.
