Question

Seasons change due to the change in position of the

Answer 1

We could describe a season as the division of a year on the basis of changes of climate along with the environment and also the sunshine hours of a particular area. The planet earth takes 365days revolve around the sun and this revolution is significant in seasonal changes.

Complete step-by-step solution:
In the question, we are asked to find change in position of what causes the change in seasons over a year. What we have to understand here is that there would have been no point of seasons if the axis of the earth had been straight. You may recall that the rotation of the earth about its axis causes day and night. But the change of seasons has to do with the apparent movement of the Sun. Now let us list down the reasons for change in seasons.
(1) Earth’s tilt at an angle of $23.5{}^\circ$at the orbital plane as it revolves around the Sun which further causes the different angle of incidence of sunlight at the Earth’s surface.
(2) The apparent movement of the Sun could be considered another significant reason for the change in seasons.
Therefore, we could conclude that change in seasons is observed due to the change in the position of the earth around the sun.

Note: We could consider the earth’s axis as the nonexistent line that runs from north to the south pole. One complete rotation on its axis marks one day on earth that is, approximately 24hours. Now, the revolution of the earth around the sun takes place in a path which we call ‘orbit’.
