What do you understand by the axis of the Earth?
Answers
Axis of an planet including earth is an imaginary straight line that runs through the poles if an planet. Earth rotates from west to east on its axis around the sun, which is called the rotation of earth. It takes almost 24 hours to complete one round of to the earth. That's why we see every day that the sun rises from the east and sets in the direction of west.
Similarly, there's another change also in which when we look at the sky at night, the stars of the night sky also appear to be moving from east to west. It's main cause is
The Earth rotates on its axis in exactly 24 hours, but 23 hours 56 minutes 4 seconds. And this rotation of earth on its exis causes day and night and earth.
We understand the following terms by the "axis of the earth" :-
● The axis of the earth is an imaginary line. The inclination of the earth's axis is titled at an angle of 66½° to the plane of it's orbit. Thus the axis of the earth in it's orbit around the sun remains title to one side.
● The earth rotate on it's axis for about 23 hours 56 minutes and for 4 seconds. And this phenomena cause day and night.
● We know that the day and nights are not of equal duration ( Except near or on the Equator ). At times during the summer season days are long than night and in winter nights are longer than days.
● Behind all above information the basic phenomena is the axis of the earth.
