3 12 temperature goes down as you get higher then starts to go up then down etc why does the pressure and temperature of our atmosphere change all the time homosphere the chemical composition within sphere is relatively constant made up of tropo sphere stratosphere thermosphere heteroshpere the thermosphere upper part is called the iron sphere energy from sun to earth borealis exists in iron sphere to understand what is going on we have to look at the sun sunspots produce some sort of energy heat during big bang energy was produced and elements collided with each other energy heat now that we have heat source its starts to radiate and push out energy and thats what the sun spots do energy travels through space at a rate of 3 83x10 26 rate aka really really fast energy from sun must travel through space as it does it looses some energy by the time it reaches earth the sun is 1362 watts it is 63 300 000 watts at sun why do we not burn up from this sun energy reacts with our atmosphere and loses tons of its energy our magnetic field diverges energy particles away from our earth a lot of energy reaches first part of atmosphere hits all the particles elements in our atmosphere they react and energy is produced as light it makes sense that energy decreases going from space into thermosphere because of these reac tons once it hits mesosphere there is oxygen and ozone why does the earth have seasons when bottom half of earth is tilted towards sun southern poles are closer then when the axis tilts so the top is more towards the sun the north pole is closer the axis doesn t actually tilt it remains the same but its relationship to the sun changes O summer solstice longest day aka getting most light normally when the sun is right over the equator winter solstice we are angled furthest away from sun shortest days coldest often over equator sun hits at 90 degree angle but at poles hits at 30 degree angle at the poles the same amount of sun energy is distributed over a larger area the atmosphere is similar to the mantle and would rather have one temperature for all the atmosphere attempts to distribute heat equally everywhere convection takes place in the same system that it does inside the core
