What causes June to have more hours of daylight than December at this location?

Answer Details

June has more hours of daylight than December at a Northern Hemisphere location because of the tilt of the Earth's axis. In June, the Northern Hemisphere is tilted toward the Sun, so the Sun follows a higher and longer path across the sky, giving more hours of daylight and more concentrated heating. In December, the Northern Hemisphere is tilted away from the Sun, resulting in fewer daylight hours and weaker sunlight.

The difference is not caused by changes in the Earth's distance from the Sun, which varies only slightly and has a negligible effect on daylight hours.
