The Earth's axial tilt is the reason why the Southern Hemisphere experiences seasons opposite to those in the Northern Hemisphere. As the Earth orbits around the Sun, its axis is tilted at an angle of approximately 23.5 degrees. This tilt causes different parts of the Earth to be exposed to varying amounts of sunlight throughout the year. When the Northern Hemisphere is tilted towards the Sun, it experiences longer and warmer days, resulting in summer. In contrast, during the same period, the Southern Hemisphere is tilted away from the Sun, leading to shorter and cooler days, which creates winter. As the Earth continues its orbit, the tilt gradually changes the amount of sunlight reaching each hemisphere, causing them to experience opposite seasons.
