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

heat

-- 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

air rises naturally if it is -- than the surrounding air masses= --- (or convection) lifting . -- lifting = two large air masses of different densities meet. their boundary is a front. the -- warm air rises above the -- denser air

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

atoms in water or air are consistently in motion this is called--

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

earth had no oxygen present ---

latent/liquid/gaseous

some -- is absorbed. interacts with material in atmosphere and is converted into some other form of energy---

solar/land/ ocean

absorption/ troposphere

this --- causes the --- to warm = greenhouse effect

blue

this is what causes the sky to be blue. -- light is scattered more easily than other colors. this scattered (-) light reaches our eyes making the sky blue
