chapter 28.1 Flashcards
a layer extending an average of 12km above earths surface
traposphere
occurs when air temperature with altitude and air becomes stable
temperature inversion
is a natural process in which certain gases in the atmosphere warm a planet as they absorb and emit infared radiation
greenehouse effect
how are earths atmosphereic seperated
based on differences in composition and temperature
what gas makes up a majority of the atmosphere
nitrogen(78%)
what is the second most abundant gas found in the atmosphere
oxygen(21%)
what is the other oneoercent of gases that make up the atmosphere
trace gases(mainly argon)
in the troposphere layer does temperature increase or decrease in altitude
decreases
how many layers are in the atmosphere
5
what are the names of those atmospheric layers starting closest to the surface
troposphere, stratosphere, mesosphere, thermosphere, exosphere
which layer is the o-zone layer found in
stratosphere
within the stratosphere does the temperature increase or decrease
increases
within the mesosphere does temperature in crease or decrease
decrease
does the thermosphere and the exosphere impact weather
no
where does 100% of our solar radiation come from
the sun
what percentage of solar radiation is absorbed by earths surface
50%
what percent is reflected off of earths surface
5%
what percentage of solar radiation is absorbed by particles in the atmosphere
20%
what percentage of solar radiation is reflected off of particles in the atmosphere
25%
what are the three basic cloud types
stratus, cumulus, and cirrus
explain stratus clouds
layered sheet like clouds, and are associated with clouds
explain cumulus clouds
they are puffy and occur in fair weather
explain cirrus clouds
they are wispy with high altitude
what are the processes where water from the land enters the atmosphere and eventually falls back to the land
the water cycle
what are the steps to the water cycle
evaporation, transpiration, condensation, and precipitation
