stratosphere, troposphere

Question 8

role of clouds

Answer 8

warm the earths climate by trapping outgoing radiaition, cool the earths surface by reflecting incoming solar radiation

Question 9

orbital forcing

Answer 9

earths orbit around the sun changes from circular to eliptical, when earths moves closer to the sun along its orbital path, the solar energy it recieves is stronger than when it is further away
