Question

पृथ्वीवर दिन व रात्र कशामुळे होतात ?

Answer 1

The Earth is a sphere which rotates in a circular motion and projecting in the identical direction that the earth is revolving on its axis encompassing the sun. The surface facing away is colder and darker and encounters night. Because the Earth is continually spinning, the line within day and night is constantly moving to encompass the planet.
