1. Water scarcity is the lack of freshwater resources to meet water demand. As only 2% of water is available for our purposes. Out of which only 1% is readily available. (source brainly)
2. The water we consume ultimately comes from the sea: because of sunlight, water heats up and evaporates into the atmosphere, where lower temperatures transform steam into droplets, which create clouds. More than 97% of the water on earth is in the oceans – the rest is found in glaciers, on lands, and in the ground. (source brainly)
3. Sometimes we see water droplets on the outer surface of the glass containing ice-cold water this is because the water vapor presents in the air, on coming in contact with the cold glass of water, loses energy and gets converted to a liquid state, which we see as water droplets.
