frictional/slows/meteor/rise
Burn up is not a result of --- heating. the incoming meteor -- down as it compresses the gases of the upper atmosphere, causing air temperature around the -- to -- shooting star
mesosphere / decreases/ozone/burn
- ---- air temp reach a minimum of 139 f. - temp, minimum at the mesopause. -temperature -- due to fewer --- molecules to absorb solar UV radiation - very little oxygen and nitrogen - sufficient gases to burn up incoming debris -MOST NEAR EARTH OBJECTS --- up in this layer
troposphere/ decrease
- shows a -- in temp. with altitude -gets its warmth from the earth's surface - contains our weather system - air pollution collects here - the bulk of air and aerosols reside here - thickness varies based on its thermal character- thickest (10 miles) over the equator and thinnest (5 miles) over poles
stratosphere / increase/ozone
- shows an -- in temp with altitude -over 25 miles thick - contains 20% of the atmospheres air -this is where the ozone resides, which blocks out harmful ultraviolet solar radiation -temp, increase due to absorption of solar radiation by -- molecules. higher kinetic energy (nothing to bump into) - the cool air of the troposphere cannot rise into the stratosphere
evaporation/condensation/ redistribution

-- is the total kinetic energy of all the atoms in a substance
solid(ice),liquid(water),gas(vapor)
--- closely spaced, move less,more ordered, -- small groups of molecules are attached, rapid movement creates some disorder , --- individual molecules,move very rapidly and therefor don't attract and join, very disordered
water/small/atmosphere/ cycled/ troposphere

human actions/ natural
--- or --- events that affect incoming solar radiation may affect life on earth
troposphere/ equator/ poles
--- thickness varies based on its thermal character. Thickest (10 miles ) over --- and thinnest (5 miles) over ---
thermosphere/increase
---- in air temp. due to solar radiation - blocks most of the harmful cosmic radiation (x- ray, gamma rays, some UV) - very few gas molecules - heat energy is actually low - gases here are ionized (broken into constituent ions as solar radiation strips them of electrons) - ionized gases cause AURORAS ( interaction near the magnetic poles of electrons and protons from the sun
cirr/alto/cumulus/nimbo or nimbus/stratus / altitude/ appearance
--=high level with wispy shape, --=midlevel, ---=heap shape, --- or -- = indicates a rain cloud, --- cloud =sheet like cover the whole sky. clouds are classified on basis of --- and ---
water
--has a high heat capacity , in other words, it must absorb a lot of heat to produce a corresponding temperature increase - heat capacity of air is 1/4 then that of (-), doesn't take as much heat to raise temp. of air
polar/ionic compounds
--molecules are easy to dissolve.water disoves -- easily in water . dissolves most metals
warm/cold/cools/dew point /condensation/humidity/ water/decrease
-when cold air moves over -- water. some of the (--) water evaporates (steam, fog) . -when warm air moves over -- water , the air ---. ---= Temperature air must reach in order to become saturated. --- occurs when relative humidity of air increases enough that the air becomes saturated with moisture. --- can increase in two ways.. addition of --- and --- in temperature
scattered/ particles/ gas
EMR (electromagnetic radiation ) that reaches earth's surface, can be --. can change direction when it hits -- and -- molecules . this causes sky to be blue.
livable
Greenhouse effect keeps the earth --- warmer if there were no greenhouse effect
distance/degree
States of water are defined by the --- between water molecules and their -- of motion:
absorb/ infrared
Surfaces on earth with low albedo --- solar radiation and re-radiate it as --- (long wavelength) radiation. ex- EMR warms cement, air above it gets heated by road. comes in as EMR and heats air above it. we have liquid water because of this
carbon dioxide nitrogen and oxygen
Venus and Earth began with very similar atmosphere's rich in ---.----- and ---
water vapor / carbon dioxide
Venus is closer to the sun and had abundant -- this vapor is split into hydrogen and oxygen, hydrogen was lost to space. remaining oxygen bonded with carbon to form abundant -- which insulates planet
lighter/density/frontal/lighter/colder

water/photosynthesis
as earth cooled ,--- condensed, rain, removed co2 from the atmosphere - early primitive organisms used --- to consume co2 and produce oxygen - oxygen accumulated in oceans but not in atmosphere until about 2 billion years ago - oxygen is reactive and combined with other elements in early rocks
kinetic energy

ozone/ uv
earliest animals lived in oceans -oceans protected them from harmful solar radiation - once oxygen accumulated in Earth's atmosphere, life could be sustained on land. - this is also when the -- layer developed, protecting life on land from -- rays
