Question
1. Which of the following planets is most likely to be colder than Earth?
A. a planet with thinner atmosphere, twice as far from the sun, cover in ice
B. a planet with thicker atmosphere, twice as far from the sun, cover in forest
C. a planet with thinner atmosphere, half as far from the sun, cover in forrest
D. a planet with thicker atmosphere, half as far from the sun, cover in ice
2. Which of the following statements about greenhouse gases and the greenhouse effect is false?
a. greehouse gases are transparent to longwave thermal radiation but absorb shortwave solar radiation
b. greehouse gases reradiate thermal energy as longwave radiation in all directions
c. because greenhouse gas levels are increasing, planet earth currently emits less energy to space than it absorbes from the sun.
d. the greenhouse effect causes energy to be transferred back and forth between earth's surface and the atmosphere.
3. What does an analysis of Earth's global energy budget indicate about the global climite system?
A. its currently in equilibrium, radiating as much energy from the top of the atmosphere it absorbs.
B. its currently in equilibrium, radiating more energy from the top of the atmosphere than it absorbs.
C. its currently out of equilibrium, radiating more energy from the top of the atmosphere than it absorbs.
D. its currently out of equilibrium, radiating less energy from the top of the atmosphere than it absorbs.
4. WHich of the following is not a reason why climatologists use and rely on general circulation models (GCMs) to explain climate phenomena?
A. Jet streams, hurricanes, and other real worls weather events and patterns are emergent properties of GCMs.
B. When driven by historical forcings, GCMs approximate recently observed changes in global mean temperatures.
C. GCMs are meticulously constructed and continuously updated and therefore describe climate in perfect detail.
D. GCMs are largely driven by basic physical laws like he conservations of energy, mass, and momentum.
Explanation / Answer
1)
A. a planet with thinner atmosphere, twice as far from the sun, cover in ice
A planet with the thinner atmosphere means it has less gases to act as storing agent of heat and radiations, the much far is from the sun the much cooler it would be.If there is ice then it is also favourable to cause less in temeperature.
2)
a. greehouse gases are transparent to longwave thermal radiation but absorb shortwave solar radiation
Greenhouse gases are such gases which absorbs longwave radiations which are radiated by the surface of the earth and maintains the heat of the atmosphere which thus helps us in providing tempearate climate and not cause to fall much of the temperature and it also absorbs short wave radiations also.
3)
A. its currently in equilibrium, radiating as much energy from the top of the atmosphere it absorbs.
Generally it is seen that if the irradiance is 100 then it is absorbed by the atmosphere= 14 , reflected back by the atmosphere = 35 and absorbed by the earth = 51 then there starts the terristerial radiations in which the total 51 is radiated directly to the space = 17 and absorbed by the atmosphere = 34, so the total absorbation by the atmosphere = 14 +34 = 48 then this energy is again radiated by the atmosphere into the space. so whatever it absorbed all it radiated.
4)
A. Jet streams, hurricanes, and other real worls weather events and patterns are emergent properties of GCMs.
A climate model can predict us that it would be cold in winter, but it can’t predict us what the temperature will be on a specific day – that’s weather forecasting. Climate pattern are weather, averaged out over time - usually 30 years. Trends are important because they eliminate - or "smooth out" - single events that may be extreme, but quite rare. so the hurricanes and the jet streams are not the emergent properties
