During an orbit, the Earth's axis keeps pointing the same way in space. Sometimes the north pole is angled toward the sun (northern hemisphere summer) and at the opposite side of the orbit the south pole is angled toward the sun (southern hemisphere summer). Half way in between these extremes are fall and winter.

Nothing - Earth's axis is tilted with respect the stars and doesn't change during a single orbit.
However, the axis does wobble over time (it takes about 25,000 years to wobble around once). Its called the "precession of the equinoxes".
Think of the Earth as a giant top - when you spin a top it wobbles as it spins.

Hi. Pegminer is basically correct. Actually the Earth's tilt appears to move on the solstice. Winter's start is the shortest day, summer's start is the longest. There is also a 25,000 year or so wobble in the tilt, but I don't think that's what you mean.
