Earth Day and night model explanation

Earth rotation around its own axis is called as earth’s rotation. The earth turns counter clockwise.

Geographic North Pole or simply know as the North Pole is a point in the northern hemisphere where earth’s axis of rotation meets its surface.

Other point knows as the South Pole is where the earth’s axis of rotation intersects its surface in Antarctica.

It takes 24 hours for the earth to rotate with respect to the sun and 23 hours, 56 minutes and 4 seconds with respect to stars.

Currently, the modern day is longer than an olden day by 1.7 milliseconds. Aryabhata stated that spherical earth rotates around its own axis daily and relative motion of stars is caused by rotation of the earth.

Geometers state that earth is in a constant circular motion. Rotation of earth’s axis moves with respect to fixed stars and also moves with earth’s crust. Hence it is called polar motion.

Prepare for Science Fair Questions & Answers – Earth Rotation

  1. What causes Earth’s rotation?
    Moons gravity causes oceans to rise and fall as the earth rotates.
  2. What is meant by Earth’s rotation?
    Earth rotates in an imaginary line that passes from North and South poles of the earth. It is called the axis of rotation.
  3. What is the speed of Earth rotation?
    1000 miles per hour.
  4. How come we don’t feel the earth spinning?
    Earth spins at a rate of 1000 miles per hour whereas Sun spins at the rate of 67000 miles per hour. We don’t feel any of this motion since they are constant.
  5. How long does it take the moon to revolve around the Earth?
    27.32 days is taken by moon to revolve around the earth.
  6. Does the earth rotate from west to east?
    During prograde motion, the earth rotates eastwards. Earth rotates counterclockwise when viewed from north pole star Polaris.


Earth rotates on its own axis and revolves around the sun which causes day and night.
