You've likely heard of the hydrologic (water) cycle before and know that it describes how Earth's water journeys from the land to the sky, and back again. But what you may not know is why this process is so essential. Of the world's total water supply, 97% is salt water found in our oceans.That means that less than 3% of available water is freshwater and acceptable for our use.
