What 4 pieces of evidence are used to explain evolution?

Fossil records, geographic distribution of living species, homologous structures of living organisms, and embryology.

Fossil records are used to compare where things once lived and died.

Geographic distribution of living species show that species evolve differently in new environments.

Homologous structures show two variations.

Embryology show early stages of animals that are strikingly similar.

Hope this helps!

Ibelieve the answer is relative humidity  because it makes more sense that way. solar flares usually occur in space it doesn't affect the earth, well it could but it wont make a significant damage.  latitude is land it doesnt do anything. prevailing winds, i dont know the correct meaning for this but i doubt that affects the land so it has to be relative humidity.
