Question

What is meant by the inclination of earth's axis? At what angle is the earth's axis inclined?
​

Answer 1

The Earth is tilted on its axis. This tilting of the Earth on its axis is known as the inclination of the Earth's axis. It is because of the tilted axis of the Earth that days and nights are of varying lengths in different parts of the Earth.

about 23.5 degrees

We have seasons because Earth's axis – the imaginary line that goes through the Earth and around which the Earth spins — is tilted. It's tilted about 23.5 degrees relative to our plane of orbit (the ecliptic) around the Sun.
