Question

mention the importance of rotation and revolution of earth​

Answer 1

Answer:

Importance of rotation ...

Earth's graceful 24-hour rotation rate is one of the traits that makes our planet so friendly to life, allowing most parts of Earth to stay a nice, comfortable temperature as they are bathed in sunlight during the day and darkness at night. Each planet in the solar system has its own unique rotation rate.

Explanation:

importance of revolution....

It takes Earth 365 days (or 1 year) to make one complete revolution around the sun. ... Answer: Earth's seasons are caused by 1) Earth's titled axis and 2) Earth's revolution (orbit) around the sun. When the Northern Hemisphere is tilted toward the sun we have summer.

hope it may helps u...

Answer 2

CHARACTERISTICS OF ROTATION -

i) The earth completes one rotation from west to east on its axis in 23 hours, 56 minutes, 4.09 seconds.

ii) The earth is always tilted in the same direction as it moves round the sun.

iii) The speed of the movement at the Equator is 1660 km per hour. The speed decreases towards the poles.

INCLINATION OF EARTH'S AXIS AND ITS SIGNIFICANCE - SHORTCUT

The angle of inclination of the Earth relative to the plane of the Earth's solar orbit is 23.5 degrees. This angle of inclination, also referred to as the "tilt" or "deviation," directly influences seasonal variations on the planet. The different seasons are due to the rotational tilt of Earth's axis. Places that are tilted towards the sun experiences the summer season, while those that are tilted away from the sun experiences the winter season.

CHARACTERISTICS OF REVOLUTION-

i) The earth moves round the sun at an average speed of 29.8 km per second.

ii) The gravitational pull makes the earth move faster when the earth is closer to the sun. Thus, the speed of revolution is not uniform.

iii) The period taken by the earth to make one complete round of the sun is 365 days, 5 hours, 48 minutes and 45.51 seconds which is taken as 365 days and 6 hours.

iv) The earth's axis is always inclined to its orbital plane at an angle of 66 and a half degree Celsius.
