Warm Up # 19—Copy each statement.
Are these statements true? If not, correct them.
1. Differences in pressure cause the horizontal
movement of air.
2. Air pressure and air density increase with
altitude.
3. The sun supplies most of Earth's energy.
Vocab to Remember
evaporation--turning from liquid to gas by
adding heat
condensation--turning from gas to liquid by
removing heat
precipitation--falling from clouds as liquid or
solid
humidity--amount of water vapor in air
Patterns of movement within systems result
in interaction and change.
Most clouds form as air rises and cools
The water cycle
•Why does water evaporate?
•Why does water vapor condense?
•Why does water precipitate (fall)?
Cirrus clouds
Cirrus--very cold, high
altitudes wispy or
feathery, "tails",
(fair weather or storm
approaching)
Cumulus clouds
Cumulus--puffy, white,
"cotton balls"
--form in daytime when
heat causes evaporation
--can be fair weather
--cumulonimbus
(thunderheads), heavy
rain
Cumulonimbus clouds
•Storm clouds
Stratus clouds
Stratus--layered,
whole sky gray, no
strong air movement
steady light
precipitation
Fog
Fog--like stratus but
on surface, surface
colder, heavier at
dawn after the
ground has cooled all
night
Cloud Observation/Forecast Activity
• We will go outside to observe
the clouds and other signs of
weather.
• Complete the independent
activity as you observe
weather conditions outside.
• You will have the rest of the
class period (inside) to
complete the activity.
• Criterion D: Reflecting on the
impacts of science
• i. describe the ways in which
science is applied and used to
address a specific problem or issue
• ii. discuss and analyze the various
implications of using science and
its application in solving a specific
problem or issue, interacting with a
factor
• iii. apply communication modes
effectively
