As the Earth travels in its nearly circular orbit around the sun, it maintains a constant axial tilt of 23.4 degrees. This tilt causes the proximity of the northern and southern hemispheres of the globe to change during its annual trip around our local star. These changes in proximity and their impact on the amount of solar energy received by the northern and southern hemispheres are what causes the Earth to have seasons.
As the incline of Earth’s axis brings the northern hemisphere closer to the sun during the planet’s revolution, the light of the sun falls more directly on the northern latitudes of the Earth. For the northern hemisphere, the sun appears at its northernmost point in the sky on the day of June 21, otherwise known as the summer
