Based on my observations, the earth rotates from west to east about the axis of rotation. The counter-clockwise rotation of the earth is as viewed from the North Pole star Polaris.
My observations supporting the counter-clockwise rotation of the earth are:
- The Sun rises in the east and sets in the west.
- All celestial objects including the stars and the moon rise in the east and set in the west.
The rotation is the result of the strong geomagnetic field of the earth. It is also responsible for the formation of day and night on the planet.

The force of gravity is a major force that created the earth. As rocks and ice clumped together as they spun around the newly formed star (sun), the force of gravitational pull increased and attracted more debris (rocks and ice). The clumps of rocks, debris, and ice, therefore, grew into a planet.
Another is electromagnetic force. The spinning currents in the outer core of the earth create a dynamo effect that forms a magnetic field around the earth. This shields the earth from the solar storms of the sun hence protects life and the atmosphere.
Weak nuclear force is responsible for maintaining the heat of the earth’s interior which is critical for maintaining the dynamo effect of the outer core so the earth is protected by its magnetic field.
