Question

How do and night occur on the earth ?

Answer 1

Answer:

The Earth orbits the sun once every 365 days and rotates about its axis once every 24 hours. Day and night are due to the Earth rotating on its axis, not its orbiting around the sun. The term 'one day' is determined by the time the Earth takes to rotate once on its axis and includes both day time and night time.

Answer 2

Answer:

We get day and night because the Earth rotates on an imaginary line called an axis. During daytime, your part of the Earth is facing the sun. As the Earth rotates you move away from the sun until eventually, the sun is no longer visible. For you, this is now nighttime, but for the other side of the planet, day has just begun.

The Earth rotates on its axis once every 24 hours. We call each 24-hour period 1 day, even though we experience both daytime and nighttime.
