* Earth's Tilt: The Earth is tilted on its axis at approximately 23.5 degrees. This tilt causes different parts of the Earth to receive varying amounts of sunlight throughout the year.
* Summer Solstice: During the summer solstice, the hemisphere tilted towards the sun experiences the longest day of the year. The sun's position is at its highest point in the sky, resulting in more daylight hours.
* Winter Solstice: During the winter solstice, the hemisphere tilted away from the sun experiences the shortest day of the year. The sun's position is at its lowest point in the sky, resulting in fewer daylight hours.
* Equinoxes: During the spring and autumn equinoxes, the sun's position is directly over the equator. This means that both hemispheres receive approximately equal amounts of daylight, resulting in a 12-hour day and a 12-hour night.
In summary:
* The higher the sun is in the sky (closer to the zenith), the longer the day.
* The lower the sun is in the sky (closer to the horizon), the shorter the day.
This variation in daylight hours is the reason why we experience different seasons throughout the year.
