The Earth's tilt causes the Northern Hemisphere to receive less direct sunlight during this time of year, leading to cooler temperatures and shorter days.
Here's why:
* Earth's Tilt: The Earth is tilted on its axis. This tilt is the primary reason for the seasons.
* Less Direct Sunlight: As the Earth orbits the sun, the Northern Hemisphere receives less direct sunlight during fall. This is because the hemisphere is tilted away from the sun.
* Cooler Temperatures: Less direct sunlight means less solar energy reaching the Earth's surface, resulting in cooler temperatures.
* Shorter Days: The angle of the sun in the sky changes, causing the days to become shorter and the nights longer.
