At noon near the equator, you would look straight up to see the sun. At noon near the poles, you would look NOT straight up, but at a lower angle, across the ground. As a result, the sun?s energy is spread over a greater area near the poles, and more concentrated near the equator. So places near the equator are warmer.
It does snow in Florida, but rarely. The reason is because Florida is farther south and closer to the equator, the warmest part of the Earth. So if you're in the Northern Hemisphere, the farther south, the warmer it gets.
Florida gets fairly regular amounts of sunlight year-round, at least compared to the Northern US, so the air is typically more tropical or warmer. In simpler terms Florida is closed to the Tropics thus it is warmer.
Florida has a Deep freeze every 4-5 years and thats when you have the best chance for snow. It is not too uncommon to see Snow north of Gainesville. You guys are so close to the equator that It is so warm there. For snow to stick it must be 32 degrees. Trust me....snow isn't that great.
Because its in one of the three zones(polar, tropic, temperate). It's in the temperate zone and very close to the tropic zone so in that case its closer to the equator and the equator is where the suns rays hit the most direct.
