3. Water Cycle
The continuous movement of water between Earth’s surface and the air, changing from liquid to gas to liquid

4. Precipitation
Any form of water particles—rain, sleet, snow, or hail that falls to the earth

5. Evaporation The process in which a liquid changes into a gas
As the water vapor, or water in its gas state, rises higher and higher into the atmosphere, it cools because heat is being taken away
When cooled enough, water vapor condenses into tiny water droplets

6. Condensation The process in which a gas changes into a liquid
When enough water droplets gather, a clo udis formed
As more and more droplets gather, they become too heavy to stay in the air so they fall to the earth’s surface as precipitation

7. Run Off
Precipitation that flows across the land’s surface or falls into rivers and streams
This water slowly finds its way back to the ocean

8. Collection Some of the water flows into streams, lakes, and rivers
Some of it soaks into the ground
Lots of this water slowly finds its way back into Earth’s oceans

9. Transpiration Plants are also part of the water cycle
They remove water from the soil
Some of this water returns to the atmosphere through the plants’ leaves. This process is called transpiration

10. Grass
Early one morning, the grass was wet with dew. How did this most likely happen?
A rain cloud came down very close to the grass
Cold air caused water in the ground to wet the grass
The grass released water while making its own food
Water vapor in the air condensed on the colder grass

11. At a certain point — a temperature called the "dew point" — water vapor in the air will begin to condense (turn back to liquid water) faster than water is evaporating.
When this happens, dew forms on surfaces that aren't warmed by the heat radiated from the ground. That's why you mainly see dew on things like grass, leaves and even car roofs.
If the temperature gets low enough in the evening, dewmay undergo yet another transformation. When temperatures are low enough, dew may freeze to a solid form that we then call "frost."
If you're wondering why it's important that the evening is clear for dew formation, it's because cloudy nights hold heat closer to the ground. If the evening is cloudy, the clouds reflect heat back to the ground. When this happens, the ground doesn't cool off enough for dew to form.
