Can someone correct me please? < is what I chose.
1. The atmosphere on Planet A is about 90% carbon dioxide. The atmosphere on Planet B is about 50% carbon dioxide. Which planet has a higher surface temperature and why?
Planet A has a higher surface temperature due to the higher amount of carbon dioxide in the atmosphere <
Planet A has a lower surface temperature due to the higher amount of carbon dioxide in the atmosphere
Planet B has a higher surface temperature due to the lower amount of carbon dioxide in the atmosphere
2. Methane is the main constituent of natural gas. Choose all the following ways humans contribute to increasing methane gas:
Leaks from natural gas systems
Rotting organic matter in wetlands <
Raising cattle <
3. Pollutants come from:
natural sources
human activities
both natural sources and human activities. <
4. A substance is produced by the combustion of fuels in automobiles. Once in the atmosphere, this substance combine with water to form acid precipitation. What is this substance?
Carbon Dioxide
Nitrogen oxide
Sulfur Dioxide <
5. Why do nitrogen and oxygen atmospheric gases NOT contribute to the greenhouse effect?
They are made up of 3 atom molecules that are bound tightly so they CANNOT vibrate to absorb energy.
They are made up of 3 atom molecules that are bound tightly so they CAN vibrate to absorb energy. <

6. How do greenhouse gases contribute to global warming?
They reflect infrared energy that reaches Earth's surface and absorb the energy in all directions. This keeps the infrared energy close to the Earth's surface. <
They absorb infrared energy that reflects off Earth's surface and reemit the energy in all directions. This keeps the infrared energy close to the Earth's surface.
They reflect infrared energy that reaches Earth's surface and absorb the energy in all directions. This keeps the infrared energy away from the Earth's surface.
7. Most of the greenhouse gases produced come from which sources? (Check all that apply)
Chlorofluorocarbons (CFC) and Hydrofluorocarbons (HFC) from aerosols, cleaning agents, and refrigeration
Fracking <
Methane from rotting plant and animal matter <
Solar energy production
Burning fossil fuels in factories, ships, cars, trains <
Cutting down forests
How did I do?
4 answers
4. I have a problem with 4. ALL of them are emitted from the combustion of an automobile. Most of it is CO2 and only some of it are N2Ox or SO2 or SO3. All of them will produce acid rain. The internet says that the major portion of acid rain comes from nitrogen oxides and sulfur dioxide.
I don't agree with your answer for
5. The correct answer for 5 is not listed. The correct answer is that neither N2 nor O2 has a permanent nor a temporary dipole moment so they cannot absorb IR radiation. The best answer choice is c.
6. I don't agree with your answer for 6. They ABSORB energy.
7. I think the question is worded poorly but I can't argue too much with your answers too much. However, I'm not sure you are allowed two answers for this one so you should check to see which of two you listed is the most.
