|
The uneven heating of the planet drives what two things?
|
winds
Coriolis- surface circulation |
|
|
dynamic topography are
|
hills and valleys in the ocean
|
|
|
when does all molecular movement stop?
|
0 degrees Kelvin
|
|
|
what can happen to waves of the sun coming into the earth?
|
reflected or absorbed otherwise
|
|
|
what is the pattern in the earth's temperature?
|
constant- over a geological time
|
|
|
energy in =
|
energy out (heat budget)
|
|
|
temperature of earth based on waht?
|
incoming radiation
|
|
|
incoming solar radiation=
|
majority of radiation
|
|
|
what type of energy is insignificant in the global heat budget?
|
Geothermal energy
|
|
|
Incoming solar-
Albedo- Absorption:atmoshpere- Earth's back radiation- Evaporation- Conduction(sensible heat)- |
100%
30% 23% 16% 24% 7% |
|
|
what can light reflect off of and what is all of this energy reflected back called?
|
particles
oceans ice land clouds in atmosphere ALBEDO |
|
|
energy absorbs and messes with the Earth's Albedo when what and why
|
ice menting cases less light to be reflected
|
|
|
what is the cause of more light reflected?
|
a cooler earth
|
|
|
what is a really really good absorver of U.V. rays?
|
ozone (O3), but it has holes
|
|
|
what reacts with the ozone and thins it out?
|
CFC-chloroflurocarbons
(in sprays and repellents) |
|
|
what is the temperature of oceans? land?
|
17 degrees celcius
14 |
|
|
what type of h aet does the Earth emmit?
|
Infrared heat
|
|
|
what gasses absorb heat?
|
Water and Co2 => green house effect
|
|
|
what does the green house effect do?
|
slows heat exiting the earth
|
|
|
is the greenhouse effect positive or negative?
|
good! we would not have evolved with out it
|
|
|
what is the benefit of having Co2 and H20 in the atmosphere?
|
keeps the oxygen inside, but slows down the escape of heat
|
|
|
where must all incoming energy eventually go?
|
back out to space
|
|
|
what happens to IR heat on its way out?
|
it slows
|
|
|
If Co2 is naturally surrounding the Earth, why bad?
|
extra blanket of iton the earth further slows the exit of IR heat = temp rising quicker
|
|
|
what does the climate change directly affect?
|
the oceans
|
|
|
What is the significance with Mauna Loa involving the atmosphere?
|
hgih in atmostphere and few influence since far away but Xo2 inscefasing since the Industrial Revolution
|
|
|
why is Co2 low in the summer?
|
a lot of trees are absorbing it- which is why the ammount differs by season
|
|
|
what is the back radiatin of the Earth?
|
the 16% of radiating IR the Earth sends back.
|
|
|
What does evaporation need to change a liquid to a gas?
|
energy (24% of it)
|
