5. This is important and we could not live without it.
6. Warmer climates have ___________ rain drops during a storm as compared to rain in cooler climates.
8. When warm air filled with water vapor moves ________ up into the cool, dry, air of the troposphere, it cools down.
10. When air cools, the water vapor in the air condenses forming _________.
11. Warm air actually can hold more _____________ than cool air.
12. When the atmosphere has too much water vapor, the water molecules condense into small liquid drops that _______ around in the air.
14. When more water molecules pile on top of dust particles, they eventually form tiny liquid water droplets called _____________. More and more of this forms clouds in the sky.

1. Weather events drive the ________ of water.
3. The water cycle is also known as the _________ cycle.
4. Water _________ can be seen when heating up a pot of water on the stove, seeing the steam rising out of it.
7. The vaporization process is called _____________.
9. When water molecules come across small _________ particles in the air, they stick to them.
11. This causes some of the individual water ___________ to gain enough energy to become gaseous water instead of liquid water.
