How does sunlight affect seasons?

As Earth orbits the Sun, the inclined axis causes the Northern Hemisphere to tilt toward the Sun for half of the year (our spring and summer seasons). ... During the other half of the year (our fall and winter seasons), the axis tilts away and less than half of the Northern Hemisphere is in sunlight.

Explanation:

Seasons are caused by the Earth’s revolution around the Sun, as well as the tilt of the Earth on its axis. The hemisphere receiving the most direct sunlight experiences spring and summer, while the other experiences autumn and winter. During the warmer months, the Sun is higher in the sky, stays above the horizon for longer, and its rays are more direct.
