Earth Science in Action - The Water Cycle (VIDEO)

 
19

Water is vital to all life on Earth and covers nearly three-fourths of our planet's surface. Where does it come from? Will we use it up eventually? In The Water Cycle, students learn that the Earth has the same water supply today as it did millions of years ago. Examine the amazing process by which water is continually recycled and transported from place to place through evaporation, condensation and precipitation. Also find out how energy from the Sun drives the water cycle and how the atmosphere prevents water from slipping away from Earth. A fun, hands-on investigation demonstrates how an artesian well works, while a visit to a desalination plant showcases how salt water is purified.
