Document Summary
Legend (starting with closest to equator): a - tropical, b - dry (arid and semi-arid, c - temperate, d - continental (ours in ontario is considered continental, e - polar and alpine climates. Our climate in ontario: humid continental, with relatively hot, humid summers and cold winters. Energy from the sun passes through the atmosphere on its way in and out. Nitrogen (78%) and oxygen (21%), almost 1% of argon gas (is a noble gas, its un- reactive) Of the 0. 037 gasses left, co2, ne, he, ch4, h2 and kr make up the rest (as well as traces of other gasses) Very big differences in temperature on the planet - because we are a curved sphere, the centre of the sphere gets more radiation then the rest. As the earth rotates around the sun, and the earth is spinning you get differences in radiation which is why on the energy map the hottest section moves depending on the season.
