The periodic variation in the amount of sunshine over different places in both hemispheres of the Earth is caused by the tilt of the Earth’s axis. The Earth is tilted at an angle of 23.5 degrees, which causes the amount of sunlight to vary over the course of the year. During the summer months, the Northern Hemisphere is tilted towards the Sun and receives more direct sunlight, while the Southern Hemisphere is tilted away from the Sun and receives less direct sunlight. During the winter months, the opposite occurs with the Southern Hemisphere receiving more direct sunlight and the Northern Hemisphere receiving less. This variation in the amount of sunlight results in seasonal changes in temperature and weather patterns around the world.
