Earth and Water The water on Earth today is the same water that was on Earth billions of years ago. We are drinking the same water dinosaurs drank! About ___ of the Earth’s surface is water. Every day 40 trillion gallons of water is being cycled through the atmosphere.
Water Cycle ( 6 PROCESSES INVOLVED) evaporation - the process where liquid changes into a gas (water vapor) due to heating condensation- water vapor in the air that turns back into liquid precipitation- water in the air that falls to the earth in the form of rain, snow, sleet, or hail transpiration- vapor that comes from plants, trees, and the ground and goes into the air infiltration- water soaks into the ground- some returns to the surface, some remains in-ground run-off- precipitation that returns to earth into rivers, streams, and oceans
