EOSC 112 Final Question and answers
correctly solved
atmosphere - correct answer ✔layers of gases enveloping the earth
hydrosphere - correct answer ✔all water on earth
biosphere - correct answer ✔all living organisms in earth
lithosphere - correct answer ✔earth's crust and interior
Earth vs Venus vs Mars - correct answer ✔Earth's solar flux is the main
factor dictating its temperature
Energy Flux or Intensity - correct answer ✔Amount of energy that is emitted,
absorbed or reflected per unit per unit of time (J/m^2sec)
λ - correct answer ✔c/v
λm
Wiens Constant - correct answer ✔W/T
in µm
W is wiens constant which is 2897 µmK
Absolute Zero - correct answer ✔0 K or -273 degrees celsius
,Stefan-Boltzmanns Law - correct answer ✔F=constantT^4
Solar Constant - correct answer ✔1370 w/m^2
Average Square Metre - correct answer ✔342 w/m^2
Average Square Metre with Current Albedo - correct answer ✔240 w/m^2
Earths Albedo - correct answer ✔26% from clouds
4% earths surface
Albedo Ratings from highest to lowest - correct answer ✔Fresh snow/ice
old snow
clouds
desert
forest
water
How Hot is Earth to emit 240 w/m^2? - correct answer ✔Effecting radiating
temp =255 k or =18 degrees celsius
Mean Surface Temperature - correct answer ✔288 k or 15 degrees celsius
Difference is due to global warming
Ozone - correct answer ✔Responsible for absorbing most of the UV rays
UV is high frequency short waves
,sensible heat - correct answer ✔heat we feel, linked to temperature
latent heat - correct answer ✔heat we dont feel, not linked to temperature
(eg. freezing and condensation)
% of solar radiation absorbed by earths surface - correct answer ✔47
Increase in Latitude - correct answer ✔Decrease in Solar Radiation (greater
angle of tilt)
Net Absorption - correct answer ✔(heating) happens at lower latitudes
Net Emission - correct answer ✔(cooling) happens at higher altitudes
Without Heat Transport - correct answer ✔Poles would be colder
Equator would be hotter
Hadley Cell - correct answer ✔between equator and 30 degrees
Hot wet air rises at equator and descends at 30 degrees
Ferrell Cells - correct answer ✔between 30 degrees and 60 degrees
Polar Cells - correct answer ✔Above 60 degrees
cold dry air descends at poles, cold air flies equatorward
, air sinking - correct answer ✔high air density
high pressure at ground level
air rising - correct answer ✔low air density
low pressure at ground level
ITCZ - correct answer ✔Inter Tropical Convergence Zone
Air cooling - correct answer ✔emitting IR to outer space
Trade Winds - correct answer ✔Don't blow towards the equator, deflected
west due to Coriolis effect
As air parcels move poleward - correct answer ✔fixed eastward looks like its
heading east from the ground
As air parcels move towards equator - correct answer ✔fixed eastward looks
like its heading west from the ground
Heat Capacity - correct answer ✔amount of energy required to increase the
temperature of 1cm^3 by 1k or 1 degree celsius
Heat Capacity of Water - correct answer ✔5x the heat capacity of rock
Rapid heat transfer - correct answer ✔downward in the form of mixing
Slow heat transfer - correct answer ✔downward in the form of conduction
