The Atmosphere
Main Ideas:
 The _____________________ is divided into layers.
 The atmosphere _____________________ life from harmful _____________________ and
_____________________ the planet’s _____________________.
 _____________________ is caused by changes in the atmosphere due to the transfer of
_____________________ in one form or another.
 ___________________________is driven by the solar _____________________ from the sun.
The Atmosphere
 Atmosphere: the blanket of ________________ that surrounds our planet held by _________________
The Early Atmosphere
 Thought to be mostly _____________________and _____________________.
 Water vapor _____________________and rained to fill the _____________________.
 The first organisms used carbon dioxide to perform ___________________________ which made
_____________________.
Today’s Atmospheric Composition
 _____________________
 _____________________
 _____________________
 _____________________: which forms clouds and precipitation and absorbs heat energy
 particles: _______________________________________________________________
 ozone: a gas in the _____________ layer that absorbs harmful UV _____________________.
 Greenhouse gasses: gas molecules that _____________________
solar_____________________, trap_____________________, and can
_____________________ the _____________________ of the atmosphere.
 Carbon dioxide: _____________________
 Water vapor: most _____________________
Atmospheric Layers
 There are 5 layers of the atmosphere, divided by _____________________.
 Temperature is a measure of the average amount of kinetic energy of the particles in a material.
(motion)
 _____________________ (“Exo”- means outer)
 outermost layer with no clear boundary
 It extends into space
 _____________________ (“therm-” means heat)
 Very little air here
 Known for its __________________________of temperatures (-112⁰ F - 2000 ⁰ F)
 Layer where __________________________________________
 Produces the _____________________ _____________________ (Northern Lights)
 _____________________ (“Meso-” means middle)
 Air is very thin
 Temperature _____________________.
 Where _____________________ burn up and make
__________________________________________.
 _____________________
 Air is pretty thin
 contains the “_____________________” which is made of
_____________________that protects us from harmful UV _____________________
by absorbing it
 This is why _____________________ in the stratosphere _____________________.
 _____________________
 _____________________ layer that contains ________________________________.
 Temperature _____________________ with altitude because the Earth’s surface
_____________________ it.
 Where all _____________________ occurs
 The Sun heats the Earth through _____________________.
 The clouds _____________________ the sun during the day and
_____________________in at night.
 _____________________and _____________________ also absorb heat and help keep
it warm at night.
 The _____________________ absorbs the Sun’s radiation.
 The ground heats the air above it through _____________________. It gets
_____________________ the farther away you get from the ground.
 _____________________ TRIES to evenly distribute heat in the troposphere.
 Warm, moist air _____________________, and cool air _____________________ and
rushes in to replace it. This creates _____________________.
 It is also how _____________________ form.
 All three types of energy transfer happen in _____________________.
 Altitude is the _____________________above sea level.
 The higher you go, the less air there is.
 Pressure is the _____________________ of the air above you
 The higher you go, the less air there is, so pressure _____________________ with altitude.
