Earth's Seasons

Earth's Seasons are controlled by the Earth's axis of rotation. During the planet's orbit around the Sun, the Earth is inclined 231.5 degrees away from the perpendicular to the plane of the Earth's orbit. This consequently affects and varies the amount of solar illumination that can reach the Earth during each orbit. This is confirmed as the origin of Earth's seasons.

Summer
In Summer seasons, the Sun is geographically closer and thus more concentrated, and the days are also longer. This allows an increase in the heating progress.

Winter
In winter, the sunlight is less concentrated because the Sun is geographically further away and the days are shorter. This accounts for the low temperatures during this season.
