2. When air is compacted, or is allowed to grow
When it grows, its cools; and when it
compacts, it heats
Every 1000 meters from the surface of the
ground, the temperature is decreased by10
degrees
Altitude goes
up, and
temperature goes
down.
3. Mountains act like a shield to prevent air
flow. This explains how the leeward side is
cooler than the windward side
Air moisture gets decreased as it reaches
the leeward side making it dry
4. Hot air and cool air mix together causing a
Front
The cold air acts like a wall when warmer
air is introduced
5. When both winds meet each other and rise
into the atmosphere forming clouds
This results in random thunderstorms in
the afternoon
6. When warm pockets of air causes you to
maybe feel warmer as you go through

7. When less dense air rises to the point
where it can't any higher, like a hot air
balloon

coming if you see big high clouds in the
atmosphere
8. When water vapor changes into liquid

the high clouds reach as low as 6000 meters
The tree are, Cirrus, Cirrostratus, and
Cirrocumulus

11. Clouds that appear from 2000 to 6000
meters
They look like Cirrocumulus clouds, but
they’re bigger because they form down to
them

12. Clouds include the
Stratus, Stratocumulus, and Nimbostratus
These clouds form around
mountains, fronts, or any winds
Also can be known as fog or sometimes
rain clouds

13. When some clouds don’t fit into the
high, middle, and low classes
Some appear over lakes as an example

precipitation in them, it begins to rain
17. Rain-
A droplet of rain has a diameter of .5mm
Snow-
Snow fall starts to melt when the
temperature reaches 4˚C
And when the temperature is above -
5˚C, snow begins to clump together
18. Sleet is rain that gets really cold
Hail is ice crystals that freeze and join on
the way down
Glaze is rain that freezes when it hits the
ground
