Angle of Inclination of Earth's Axis
The Earth's axis is tilted relative to its orbital plane, and this tilt is known as the angle of inclination. Understanding this angle helps explain the changing seasons and various climatic zones on our planet.

What is the Angle of Inclination?
- The Earth's axis is tilted at an angle of approximately **23.5 degrees** from the vertical.
- This angle is measured from a line perpendicular to the orbital plane, which is the imaginary flat surface that the Earth travels around the Sun.

Significance of the Tilt
- The tilt of the Earth's axis plays a crucial role in creating **seasons**:
- When the Northern Hemisphere is tilted towards the Sun, it experiences **summer**.
- Conversely, when it is tilted away, it experiences **winter**.
- The tilt also affects the **length of days** and **intensity of sunlight** received at different latitudes throughout the year.

Effects of the Angle
- Different regions of the Earth receive varying amounts of sunlight depending on the angle of the tilt.
- Areas near the equator experience less variation in temperature and daylight hours, while polar regions face extreme variations.

Conclusion
Understanding the Earth's axial tilt is essential for grasping how it influences our climate and seasons. This **23.5-degree tilt** creates a dynamic environment that shapes life on our planet.
