Seasonal Variation on Earth

What causes the difference in seasons between the Northern Hemisphere and the Southern Hemisphere?

The difference in seasons between the Northern Hemisphere and the Southern Hemisphere is caused by Earth's tilted axis. This tilt causes the amount of sunlight received by each hemisphere to vary throughout the year.

Explanation:

Earth's axis is tilted at an angle of approximately 23.5 degrees relative to its orbital plane around the Sun. This tilt is the reason why we experience different seasons on Earth.

As Earth orbits the Sun, different parts of the planet receive varied amounts of sunlight. When a particular hemisphere is tilted towards the Sun, it receives more direct sunlight and experiences summer. Conversely, when a hemisphere is tilted away from the Sun, it receives less direct sunlight and experiences winter.

Due to Earth's tilted axis, the Northern Hemisphere experiences winter while the Southern Hemisphere experiences summer, and vice versa. This is why the seasons are reversed between the two hemispheres.
