troposphere
a layer extending an average of 12 km above earths surface.
temperature inversion
occurs when air temperature increases with altitude and the air becomes stable
greenhouse effect
is a natural process in which certain gases in the atmosphere warm plant as they absorb and emit infra ire radiation.
describe the layers of the atmosphere and how temperature changes with altitude
Temperature increases as you gain altitude in the stratosphere and the thermosphere. Temperature decreases as you gain altitude in the troposphere and mesosphere. increase as you ingress in the stratosphere
define the green house effect
The greenhouse effect is a process that occurs when gases in Earth’s atmosphere trap the Sun’s heat.
explain why earth’s atmosphere today contains more oxygen than earth’s early atmosphere
solar radiation split water molecules and cyanobacteria began the process of photosynthesis.
compare and contrast cirrus cumulus and stratus clouds
Stratus/strato: flat/layered and smooth. Cumulus/cumulo: heaped up/puffy, like cauliflower. Cirrus/cirro: high up/wispy.
think critically how might an increse in avarage atmosphere temperatures affect the water cycle
more water evaporates into the air
how are atmospheric layers divided
composition and temperate
what is the majority of the troposphere made up of
nitrogen 78%
what is the second biggest gas that makes up the air in the atmosphere
oxygen 21%
what are the remaining one percent made up of
trace gasses the majority is made up of argon
what is selector aspiration
breathing
tropesherere
this is where weather takes place
does the temperature incerese or decrese in the thropesphere
it decreses
how many layers are in the earths atmosphere
there are 5 layers
where does 100% of our solar radation come from
sun
what percent of solar radiation is adsorbed by earths surface
50%
what percent of solar radiation gets reflected off of earths surface
5%
what percent of radition is abosorb by particales in the atmosphere
what percnt of soalr radaition is reflected back
25%
what are the three basic cloud types
stratus cumulus cirrus
explan what a startes cloud looks like
they are layerssheet like clouds assossiaded with rain
explan what do cumuless cloud look like
they are puffy and cause fair weather
cirrius clouds
there wispy and high altitude
1 what is it called where water gets takken from the lands surface
2 what are the stages of the water cycles
evaporation transportation condensation percipitation ilfiltration
jet stream
is a narrow band fast moving high altittude air
coriolis effect
the apparent deflection of an abject due to earths rotation
air mass
is a large volume of air with uniform mostuior and temputaure throughout
weather front
air masses interact in zones
