Which physics relationship is more important?

How the increase in temperature vs. depth for Earth (creates the "oil window"--7,500 feet to 15,000 feet--where dead organisms were cooked into oil).
How the absorption of infrared radiation by gases in Earth's atmosphere depends on wavelength; the resulting greenhouse effect provides us with temperatures that enable life to flourish.



Which unanswered question in physics is more important?

Do black holes evaporate? (as per Stephen Hawking's prediction)
Must the properties of the universe enable us to evolve to observe it? (This idea is called the anthropic principle.)
