Question

1)What is the angle of inclination of the earth axis with it's orbital plane?
2)define rotation and revolution

Answer 1

1. That's logical, but not the case for Earth. Instead, Earth has seasons because our planet's axis of rotation is tilted at an angle of 23.5 degrees relative to our orbital plane, that is, the plane of Earth's orbit around the sun. The tilt in the axis of the Earth is called its obliquity by scientists. Obliquity.

2.the movement of earth in its own axis is called rotation.

the movement of earth around the sun is called revolution
