Document Summary
Seasons occur because the earth is tilted on its axis: as it tilts on its axis, different portions of the earth receive different amount of sun. In summer, northern hemisphere is tilted towards sun so there is a greater amount of solar energy coming into that hemisphere. In equinox, the axis is more straight up, the line of illumination pretty much goes through the middle of the planet. In winter, northern hemisphere is tilted away from the sun: therefore, amount of heat that enters the earth (particularly at the poles) varies by season. Solar convection: heat provides the mechanism by which circulation happens. It happens through solar convection: example: heater radiates heat. The air around it gets warmer (warmer air is less dense). Warm air will rise and move to the other side of the room where the cold window is. Molecules being to get closer to get her and move slower.
