Question

DEFINE THE FOLLOWING TERMS

1. WATER CRISIS

2.cloud formation

3. water cycle

4. water conservation ​

Answer 1

Answer:

1. Water crisis is the lack of freshwater resources to meet the standard water demand. Two types of water scarcity have been defined: physical or economic water scarcity. Physical water scarcity is where there is not enough water to meet all demands, including that needed for ecosystems to function effectively

2.A cloud is nothing but a body composed of water droplets and ice crystals that consolidate and float in the sky. Clouds are very crucial in determining weather and are very helpful in predicting the weather as well. There are various kinds of clouds, and they get their name in two primary ways. While some of the clouds are formed high up in the sky, there are also some clouds which are formed close to the surface. The clouds that touch the ground are referred to as fog. Clouds are also named by their shape, and cirrus clouds refer to high clouds while cumulus clouds are middle clouds.

explaination

Now coming to the question, how are clouds formed? The cloud formation process starts with suspended water droplets and ice crystals that condense in the sky. Some amount of invisible water vapor is always present in the air, and this water vapor is the first step in the cloud formation process. With the fall in temperature, condensation of water vapour takes place, which causes the vapour to change to liquid form. Here in this area, the air is saturated with vapour, which results in the formation of clouds. 

3.The cycle of processes by which water circulates between the earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration.

4.Water conservation is the practice of using water efficiently to reduce unnecessary water usage. According to Fresh Water Watch, water conservation is important because fresh clean water is a limited resource, as well as a costly one.
