Question

what is meant by the inclination of Earth's axis? ​

Answer 1

Answer:

The axis of the Earth is tilted at an angle of 23 1/2° from a perpendicular to the orbital plane. This tilting of the axis is called the inclination of the Earth's axis. Due to this inclination, the axis of the Earth makes an angle of 66 1/2° with the plane of the Earth's orbit.

Answer 2

Today, the Earth's axis is tilted 23.5 degrees from the plane of its orbit around the sun. But this tilt changes. During a cycle that averages about 40,000 years, the tilt of the axis varies between 22.1 and 24.5 degrees. Because this tilt changes, the seasons as we know them can become exaggerated.
