Angle of Inclination of Earth's Axis with the Orbital Plane

The angle of inclination of Earth's axis with the orbital plane is the angle between the axis of rotation of the Earth and the plane of its orbit around the Sun. This angle is also known as the obliquity of the ecliptic and is the reason why we have seasons on Earth.

Measurement

The angle of inclination of Earth's axis with the orbital plane is currently about 23.5 degrees. This angle is not constant and changes slowly over time due to factors such as gravitational pull from other planets and the Moon.

Effect on Seasons

The angle of inclination of Earth's axis with the orbital plane is what causes the seasons on Earth. When the Northern Hemisphere is tilted towards the Sun, it is summer in that hemisphere. When it is tilted away from the Sun, it is winter. The opposite is true for the Southern Hemisphere.

Impact on Climate

The angle of inclination of Earth's axis with the orbital plane also has an impact on climate. Areas near the equator receive more direct sunlight throughout the year, leading to a warm and humid climate. Areas near the poles receive less direct sunlight, leading to a colder climate.

Conclusion

In conclusion, the angle of inclination of Earth's axis with the orbital plane is an important factor that affects the seasons and climate on Earth. It is currently about 23.5 degrees and changes slowly over time.
