Effect of the Tilted Axis on Day and Night

The tilt of Earth's axis plays a crucial role in the variation of day and night durations throughout the year.

What is Earth's Tilted Axis?

Earth’s axis is tilted at approximately 23.5° relative to its orbit around the Sun. This tilt causes different parts of Earth to receive varying amounts of sunlight at different times of the year.

How the Tilt Affects Day and Night

  • During summer solstice in the Northern Hemisphere, the North Pole is tilted towards the Sun, resulting in longer days and shorter nights.
  • During winter solstice, the North Pole is tilted away from the Sun, causing shorter days and longer nights.
  • At equinoxes, the tilt is such that day and night are approximately equal worldwide.
  • The variation in day length causes changes in temperature and seasons.

Conclusion

The tilt of Earth's axis leads to changes in the duration of day and night throughout the year, causing seasons and influencing life on our planet.
