ATMOSPHERE
AND WEATHER
ATMOSPHERE
• The atmosphere is a blanket of
_______________ that covers a planet.
• Atmospheres tend to get ___________ dense
as you travel away from the planet.
• The air molecules get __________________
apart.
• There are _______main levels of Earth’s atmosphere.
•
a.) The closest layer to earth is called the
_________________________.
•
b.) The second layer is called the
______________________________.
•
c.) The third layer is called the
_______________________________.
•
d.) The last layer is called the
_______________________________.
• 1. This layer also has two layers within it. There are
called the ____________________ (which is closer to
earth) and the ____________________ (which is the
farthest part of the atmosphere).
• Layers of the atmosphere start at different altitudes.
• The troposphere starts at _________km and
extends to around _________km.
• The stratosphere starts at ________km and
extends to ________km.
• The mesosphere starts at _______km and
extends to ________km
• The thermosphere starts at _______km and has
no ______________.
• The layers are divided based on their
________________________.
• The temperature in the troposphere and the
mesosphere ______________________ as
you move farther from earth.
• The temperature in the stratosphere and the
thermosphere ______________________ as
you move away from earth.
• Each layer is unique and has different events or serves
different functions.
• In the troposphere you would expect to find
___________________. This is the densest layer of the
atmosphere.
• In the stratosphere you would find the
_________________ which protects us from the sun, or
see ______________ flying.
CONTINUED…
• In the mesosphere you would be able to see
_________________ burning up since this layer
protects us from collisions. This is the coldest layer of
the atmosphere.
• In the thermosphere you would expect to see the
________________ ________________ or a
___________________ orbiting. This is the hottest
layer of the atmosphere.
ENERGY IN THE ATMOSPHERE
• The energy from the sun travels in waves. Different types of
energy have _____________________________ wave lengths.
• Most energy from the sun reaches the earth in three different
forms:
• _______________________radiation which come to the earth as
heat ( _______________waves).
• ______________________radiation which is harmful and can give
you sunburn (____________________ waves).
• __________________ __________________ which we can see as
colors
( _____________________ waves).
• Some of this energy is _____________________,
while the rest is reflected off snow, clouds, water
and other surfaces.
• The _________________________helps hold
much of this energy close to the earth. When
heat is held close to the earth in this way it is
known as the ________________________
_________________________.
CLIMATE CHANGE
• Climates change very ___________________, but can have
______________ effects on living things in an area.
• Scientists study climate change through
____________________, ________________
_____________________, and _____________________.
• Earth’s climate has changed several times in its history.
Earth goes through warm periods as well as
________________ periods know as ___________
_______________.
• There are _________________ and _________________
causes of climate change.
• Natural causes include: the distance between earth and the
_____________ as well as the ___________ or tilt of the
earth. Also changes in the amount of _______________ the
sun gives off and movement of the __________________.
These are slow changes that can cause major changes in
climate.
• Human factors include: the adding of _________________
from burning coal and oil to the atmosphere. These gasses
hold extra _______________.
• Effects of Global warming
• Positive effects include warmer climates for farmers to grow
extra ______________.
• Negative effects include a rise in ocean temperatures which
could cause a greater number of powerful ________________.
This could also cause melting of the __________________
which would _______________ the sea level. Finally climates
changes could kill many organisms that cannot _____________
fast enough to the changing environment and may cause them
to go ______________________.
