Question

compare importance of air and water

Answer 1

Air is a third critical resource for humans, plants, animals and all other organisms within a natural area. Air must be monitored in order to control and lower pollution levels, control smoke caused by wildland fires, and to monitor air quality. Water is one of the most important natural resources flowing from forests. The Forest Service manages the largest single source of water in U.S., with about one-fifth originating from 193 million acres of land which provides drinking water to 180 million people every day.

Answer 2

While the oceans contain most of the planet's water, water also exists as ice and water vapor. Air is important because it helps water move between these states in a process scientists call the water cycle. Heated by the sun, surface water evaporates into the air and becomes water vapor. As temperatures drop, water vapor forms clouds as it condenses. Clouds return water to the ground in the form of rain, sleet or snow. Because clouds move, they often transport water to locations far from where the water originated. The water cycle ensures that life around the planet receives the water it needs. It also helps replenish lakes, rivers and other waterways.
