1. How is the radiation emitted from the Earth different from radiation emitted from the sun?

Hi. 4? Jeez. 1) The Sun emits while the Earth reflects. 2) Oceans absorb CO2 and life converts it to other compounds. 3) Without tilt there would be no summers or winters. 4) Gravity holds the particles, mostly atoms, of gas to nearby the gravity field, but you'll notice that hydrogen is remarkable absent. Too light weight.
