How Does Water Return to the Earth's Surface

Water is the only substance that naturally exists in three states on Earth solid liquid and gas. Water at the Earths surface evaporates into water vapor which rises up into the sky to become part of a cloud which will float off with the winds eventually releasing water back to Earth as precipitation.
