*evaporation = when a liquid changes to a gas *condensation =when gas changes to liquid *precipitation = any form of water that falls from the sky

What is runoff? When some precipitation flows downhill on Earth surface
What causes rain? Water in lakes, oceans, and rivers evaporates and becomes water vapor. As water vapor rises in the air, it cools and condenses into water droplets. These droplets form clouds. As more water vapor condenses, the drops become heavier and heavier. They become so heavy, they fall to Earth as precipitation.
