Unit 2 Studying (Earth Science)

2. When two air masses with different conditions collide.
8. Energy transfer by touch.
9. (two words, no space) The gaseous form of water; clouds are made of this!
11. In order for a cloud to form, the temperature needs to be ____.
12. The second layer of the atmosphere, where the ozone layer is found.
13. The layer of gasses that surrounds the earth.
16. (two words, no space) When cold air moves really fast towards warm air, pushing the warm air up and over it, it's called an ________ _____.
18. Long-term patterns in atmospheric phenomena (usually the average over 30 years).
20. The most common gas in the atmosphere.
21. The general term for water falling from clouds (rain, snow, etc).
23. The fourth layer of the atmosphere, which absorbs a LOT of solar radiation so it's super hot!
25. Energy transfer by the movement of heated fluids (like when the hot water moves around in a pot of boiling water).
26. The gasses acting like a "blanket" and trapping heat on earth is called the "__________ Effect".
27. The third/middle layer of the atmosphere, which doesn't absorb much solar radiation.
29. The second-most common gas in the atmosphere.
30. Clouds that form below 2000 meters are called ___ Clouds.
31. Tall clouds that can exist across multiple cloud levels, which are responsible for a lot of thunderstorms.

1. (two words, no space) When two air masses meet but neither is moving much, it's called a _________ _____.
3. The closest layer of the atmosphere to the surface of the Earth.
4. (two words, no space) A border between the wind zones caused by the Coriolis Effect. These are where large storms/weather systems form!
5. (two words, no space) When warm air moves towards cold air, it's called a ____ _____.
6. (two words, no space) A tiny particle of dust/ice/etc which acts as a surface for condensation; necessary to form a cloud.
7. Energy transfer by waves (like through light).
9. Short-term variation in atmospheric phenomena.
10. (two words, no space) A bunch of air that has picked up the conditions of the nearby area (for example, hot and humid).
14. The outermost layer of the atmosphere. Past this, you're in space!
15. (two words, no space) When cold air moves towards warm air, it's called a ____ _____.
17. This special gas is found in the stratosphere, and helps protect us from harmful radiation from the sun!
19. Clouds that form between 2000 and 6000 meters are called ______ Clouds.
22. The earth is constantly rotating, meaning the fluids on earth are always moving too. This causes something called the _______ Effect.
24. Besides temperature and humidity, this is an important factor for weather. When this is high, weather is nicer, but when it's low, there's often clouds and precipitation.
28. Clouds that form above 6000 meters are called ____ Clouds.
