Question

In astronomy what is the difference between rotation and revolution?

Answer 1

Hint : Astronomy is the study of sun, moon, stars, planets, non-earthly bodies and other phenomena. Rotation is the spinning of earth around its own axis and revolution can be used as a synonym for rotation, it is commonly used when one body moves around another.

Complete Step by step solution:
Rotation is responsible for the day and night to occur and revolution is responsible for occurrence of seasons.
The Earth rotates on its own axis and it rotates within the eastward direction and in an exceedingly counter-clockwise prograde motion. Therefore, the direction of earth’s rotation is taken into account as from west to east. the earth rotates once in twenty-four hours. Since Earth rotates from west to east, the moon, sun, and every one different celestial body seem to move from east to west. This gives the best explanation of sunrise and sunset. The rotation of the Earth is the reason behind the formation of day and night.
Seasons are due to Earth’s revolution around the Sun and because of the tilt of the Earth on its axis. The hemisphere receiving the foremost direct daylight experiences spring and summer, whereas the opposite experiences autumn and winter. During the hotter months, the Sun is higher within the sky, stays higher than the horizon for a longer time, and its rays are direct. During the cooler time, the Sun’s rays aren’t as sturdy and it’s lower within the sky. The tilt causes these dramatic variations.

Note:
Earth is not perfectly round but spherical in shape.
Equinox can be defined as time when the sun crosses the celestial equator such that the length of night and day becomes the same and at the same time the length of latitudes L degree North and L degree South. There are two equinoxes every year.
