Why does the sun move further north in winter?

The sun appears to move further north in winter due to the tilt of the Earth's axis. As the Earth orbits the sun, its axial tilt causes different regions to receive varying amounts of sunlight throughout the year. During winter in the Northern Hemisphere, the axis is tilted away from the sun, resulting in shorter days and lower sun angles, making it seem as though the sun is moving north in the sky. This phenomenon is part of the seasonal changes experienced on Earth.
