| What is the Hydrologic Cycle? |
| The Hydrologic Cycle, also called the water cycle, is the process that moves water around the earth. The cycle starts with the sun heating water in our rivers, lakes and oceans and turning it into water vapor, which evaporates or rises into the air. When water vapor cools it forms condensation or clouds, which become heavy with water and produce rain or snow (otherwise referred to as precipitation) that returns to the earth.
