Question

(a) What is the angle of inclination of the earth's axis with its orbital plane?


(b) Define rotation and revolution

(c) What is a leap year? ❓❓
​

Answer 1

Explanation:

4 Earth's declination angle. The earth's axis of rotation is tilted 66.5 degrees with respect to its orbital plane around the sun and its axis of rotation is inclined 23.5 degrees from the perpendicular, with respect to this plane.

(b) Rotation is the movement of the Earth on its axis. Revolution is the movement of the Earth around the Sun in a fixed path or orbit.

(c) It takes approximately 365.25 days for Earth to orbit the Sun — a solar year. We usually round the days in a calendar year to 365.
