2. layer of air and gases that surrounds the Earth. It’s where weather happens
3. the condition of the atmosphere at a place for a short period of time, including humidity, cloud cover, temperature, wind, and precipitation
6. When liquid water gets warm and turns into water vapor (a gas) that goes into the air, like when a puddle dries up.
7. general pattern of weather in an area over a long period of time [30 years or more (many decades)]
8. cycle the change of water from one state to another as it moves between Earth’s surfaces to the atmosphere
9. The process where plants release water vapor into the air through tiny openings in their leaves.
10. Water that flows over the ground and into rivers, lakes, or oceans after it rains or snows.

1. When water vapor in the air cools down and turns back into tiny drops of liquid water, like when clouds form.
4. Water that falls from the sky as rain, snow, sleet, or hail
5. energy The light and heat that comes from the sun, which powers processes like evaporation
