How does the water cycle work?

Historian
How much water is on earth and how much water is available for humans?
•70 percent of freshwater is locked in ice caps
• Less than 1 percent of the world's freshwater is readily accessible
• 6 countries (Brazil, Russia, Canada, Indonesia, China and Colombia) have 50 percent
of the world's freshwater reserves
• One-third of the world's population lives in "water-stressed" countries, defined as a country's ratio of water consumption to water availability. Countries labeled as moderate to high stress consume 20 percent more water than their available supply.

How does the water cycle work?
In the hydrological cycle, water from oceans, lakes, swamps, rivers, plants, and even you, can turn into water vapor. Water vapor condenses into millions of tiny droplets that form clouds. Clouds lose their water as rain or snow, which is called precipitation.

-Turn off the faucets when not in use, such as brushing your teeth or washing dishes
-Water at dawn or dusk to avoid evaporation
