Question

State the reason for variation in the time of sunrise and sunset at different places on the Earth?​

Answer 1

Answer:

To put it very very very simply, it's because the Earth has a tilted axis. As it orbits around the sun, very often either its northern half or its southern half is closer to the sun than the other. This changes as the Earth's position in its orbit changes.

Answer 2

Answer:

Because of the Earth's tilt on its axis, the path of the Sun across the sky varies, and therefore, the rising and setting time changes. At different locations on Earth, the rising and setting times vary because the portion of the celestial sphere visible from different locations of Earth is different.
