They converted carbon dioxide to oxygen. The increased oxygen levels allowed for cellular respiration to occur instead of only glycolysis. The atmosphere became thinner, decreasing temperatures of the planet as well.
Answer:
For example, air with a large amount of water vapor is less dense than dry air because the water molecule has less mass than either an individual nitrogen or oxygen molecule. Also as elevation or altitude increases, air becomes less dense. Unequal heating of the Earth's surface also forms large global wind patterns

How many can you check? I personally think its all 4 but i could be wrong :)
