I know it sounds funny, but check this out. It all adds up to a whopping 1,300 gallons of water for one simple hamburger. The earth's water is in constant motion called the water cycle. There's evaporation, condensation and precipitation. Rain and snow constantly replenish the waters in our rivers and lakes, but it can take hundreds of years to replace the water underground in aquifers.
Plants also play a role in the water cycle.
They release water into the air through a process called transpiration. It works just like evaporation does with the ocean. Mac users, press command in place of ctrl. 2000-2001 WZZM 13. All rights reserved.
