some scientists propose that life on earth could have formed from primitive conditions, like those illustrated in the urey-miller experiment model shown above. however, more recent analysis indicates that the atmospheric components might be different than is shown above. if high rates of volcanic activity were responsible for the atmospheric conditions in the atmosphere, what modifications to the model might be necessary?
a) water vapor should be present in higher concentrations, as volcanic activity would cause more water to evaporate.
b) oxygen gas should be present in higher quantities, as photosynthesis would be occurring at a higher rate after volcanic activity.
c) ozone would be present in higher quantities, as volcanic activity would increase the combination of free oxygen atoms into ozone.
d) carbon dioxide, sulfur dioxide, and hydrogen sulfide should be present in higher concentrations than are depicted above, as they are emitted from volcanic eruptions.

Melissa lives in a town called greendale. she discovers that when she lights a match and holds it near her kitchen faucet, the little flame grows into a larger fire. melissa is surprised because she thought the water would extinguish the flame rather than ignite it further. her mother tells her that the water might be contaminated with dissolved methane, a primary component in natural gas. melissa investigates the matter and finds that cases of methane contamination started shortly after a company began fracking for natural gas in the area. based on this information, which three statements are plausible consequences of fracking in greendale?
