How Fast Does the Earth Spin?
A quick answer, The circumference of the earth is about 25,000 miles. The earth spins 25,000 miles in 24 hours. The speed in miles/h is 25,000/24=1,042miles/hour. Scientifically, That depends on where on Earth you are standing. At the poles, the Earth hardly spins at all, but as you travel towards the equator, the rotational speed picks up. This makes sense — as the circumference of a circle increases, a single point along it has to travel faster to complete a revolution in the same amount of time. The rotational speed of the Earth at the equator is about 1,038 miles per hour. The atmosphere at the equator is also slightly thicker due to rotation, and you weigh slightly less. At mid-latitudes, the speed of the Earth’s rotation decreases to 700 to 900 miles per hour. If the Earth were to stop spinning suddenly, the atmosphere would still be zipping along nicely at around 1,000 miles an hour. As a result, everything not attached to bedrock would pretty much be scoured clean. If you have
One of the basic questions regarding the earth is, how fast does it spin? The earth is constantly spinning; it spins around its axis. An axis in this case is an imaginary line running through the center of the earth from the North Pole to the South Pole. To calculate how fast the earth spins, we need to know a few details.
