Question
How does the Earth’s tilt affect the seasons?

The Earth's tilt plays a crucial role in the changing seasons throughout the year. Here’s how it works:
1. **Axial Tilt:** The Earth is tilted on its axis at an angle of approximately 23.5 degrees. This tilt is consistent as the Earth orbits the Sun.
2. **Uneven Sunlight Distribution:** Because of this tilt, as the Earth moves along its orbit around the Sun, different parts of the Earth receive varying amounts of sunlight at different times of the year.
3. **Summer and Winter:** When the Northern Hemisphere is tilted toward the Sun (around June 21, the summer solstice), it experiences summer due to more direct sunlight and longer days. Conversely, when the Northern Hemisphere is tilted away from the Sun (around December 21, the winter solstice), it experiences winter, resulting in less direct sunlight and shorter days. The opposite occurs in the Southern Hemisphere.
4. **Spring and Autumn:** During the equinoxes, around March 21 (vernal equinox) and September 23 (autumnal equinox), the tilt of the Earth is such that both hemispheres receive approximately equal amounts of sunlight. This results in mild temperatures characteristic of spring and autumn.
5. **Temperature Variations:** The angle of sunlight affects the intensity of solar energy received at different latitudes. Regions at the equator receive sunlight more directly year-round, leading to a warmer climate, while regions at higher latitudes experience greater seasonal temperature variations.
In summary, the Earth's axial tilt is responsible for the different seasons, influencing the amount of sunlight and temperature experienced in different regions throughout the year.

The Earth's tilt of about 23.5 degrees affects the seasons by changing how sunlight strikes different parts of the planet. When the Northern Hemisphere tilts toward the Sun, it experiences summer; when it tilts away, it experiences winter. The equinoxes bring equal sunlight to both hemispheres, resulting in spring and autumn. This tilt causes variations in temperature and day length throughout the year.
