The sun is a star therefor it moves just as stars do. However, if you mean the path of the sun through our sky then the difference is purely due to distance! The earth moves around the sun, not the other way around! As for the seasons, the change is due to the earths tilt towards or away from the sun, when the northern hemsiphere is tilted towards the sun the north has summer and the south winter, and vice versa.

actually my astronamy teachers says thats actually incorrect, i would tell u the correct answer if i had my book on hand, but ur in correct on both counts ...sorry. but nice try...u get an a for effort.

The sun moves, as all stars in our galaxy do, around the centre of the Milky Way. Other stars moved around the galaxies they are in. The seasons are caused by the tilt of the earth. The earth's tilt exposes one hemisphere closer to the sun at one time of the year, and further from the sun at another one. That means that, when that hemisphere is closer to the sun, it has summer. When it is further, it has winter. The tropics, since they do not move closer or further, have only a wet and dry season, caused by the wind directions, but no true summer and winter.

yeah i know im just messing with u. as far as ur degree of education its prob high but i doubt its higher then his unless ur steven hawkings or even his assitant.

I have not seen an answer that is entirely correct with respect to what causes the seasons. What causes the seasons is the fact that Earth's axis is tilted 23.5 degrees from perpendicular to Earth's plain of revolution. Earth's axis points toward the same point in the sky all year round. This means that its orientation to the Sun changes as Earth orbits the Sun. So, at some times of the year, the North Pole is tilted toward the Sun and at other times of the year, it is pointed away. At those times that the north pole is pointed toward the sun, the northern hemisphere gets more direct sunlight and longer days. The more direct sunlight means that any given unit of surface area is going to receive more light. The longer days mean more time to heat the surface. These two factors combine to cause warmer temperatures. When the north pole is tilted away from the Sun, then the northern hemisphere gets less direct sunlight and shorter days. This leads to cooler weather. This also explains why the southern hemisphere has its season opposite of the northern hemisphere. When the north pole is tilted toward the Sun, then the southern hemisphere is tilted away from the sun and vice versa.
