WHY sun higher in summer?

The sun appears higher in the sky during summer due to the tilt of the Earth's axis. As the Earth orbits the sun, the Northern Hemisphere is tilted towards it around June, resulting in more direct sunlight and longer days. This increased solar angle leads to warmer temperatures and the characteristic summer season. Conversely, during winter, the Northern Hemisphere is tilted away from the sun, causing lower sun angles and shorter days.
