14. Since CO2 and water vapor are both greenhouse gases, they absorb infrared radiation to help maintain a stable temperature.
15. (a) Natural process: Burning coal and the industrial process
Human activity: Breathing and bacterial decay
(b) Natural process: Decomposition of plants and animals
Human process: Fossil fuels and raising livestock

16. It would cause the average surface temperature to increase, which would be an increase in greenhouse/ atmospheric gases, which causes higher pressure. It would decrease if there was a decrease of greenhouse/atmospheric gases that causes lower pressure.
17. A greenhouse with transparent glass walls is warmer than a structure with dense wooden walls because infrared light cannot escape through the glass.
18. a.
19. Atmospheric CO2 gas, solid calcium carbonate, natural gas and organic molecules.
b.
19. Atmospheric CO2 gas, solid calcium carbonate, natural gas and organic molecules.
20. It could be part of the atmosphere as a gas as a result of photosynthesis, in the lithosphere as a plant or animal waste decay, or part of the hydrosphere as limestone.
