🌍 Understanding Earth's Seasons

Read the following explanation carefully:

Many people think that Earth's seasons are caused by our planet being closer to or farther from the Sun at different times of the year. This is actually incorrect! The real reason for seasons is much more fascinating.

Earth's seasons are caused by the tilt of our planet's axis. Earth is tilted at an angle of approximately 23.5 degrees as it orbits around the Sun. This tilt means that different parts of Earth receive varying amounts of direct sunlight throughout the year.

When the Northern Hemisphere is tilted towards the Sun, it receives more direct sunlight and experiences summer. At the same time, the Southern Hemisphere is tilted away from the Sun, receiving less direct sunlight and experiencing winter. Six months later, the situation reverses - the Southern Hemisphere tilts towards the Sun (experiencing summer) whilst the Northern Hemisphere tilts away (experiencing winter).

The angle at which sunlight hits Earth's surface is crucial. When sunlight hits at a steep angle (more directly), the energy is concentrated over a smaller area, creating warmer temperatures. When sunlight hits at a shallow angle (less directly), the same amount of energy is spread over a larger area, resulting in cooler temperatures.

This is why in New Zealand (Southern Hemisphere), we experience summer during December, January, and February, whilst countries in the Northern Hemisphere like England and Canada are experiencing winter during these same months.
