The earth rotates at approximately 1000 mph. If a full rotation takes 24 hours, the earth should then be 24000 miles in diameter, however, the earth is only 7917.5 miles in diameter. How is this possible?
The misconception here is based on a misunderstanding of how the Earth's rotation affects its size. The Earth's rotation does not determine its diameter.
The Earth's equatorial rotation speed is approximately 1670 kilometers per hour (1037 miles per hour), not 1000 mph as mentioned. The 24-hour rotation period refers to the time it takes for the Earth to complete one full rotation on its axis.
The Earth's diameter is indeed approximately 7917.5 miles (12,742 kilometers), and this measurement is not directly related to the rotational speed. The diameter is a measure of the distance across the Earth at its widest point, passing through its centre.
The rotational speed is a measure of how fast a point on the Earth's surface is moving due to the Earth's rotation. The equator experiences the highest rotational speed, while the rotational speed decreases as you move toward the poles.
In summary, the Earth's diameter is not determined by its rotation speed; it is a fixed measure of the distance across the Earth. The rotation speed is a measure of how fast points on the Earth's surface are moving due to the Earth's rotation.
