What is the rotation of the Earth?
Earth rotates eastward on its axis at an average speed of roughly 1,000 miles per hour, or roughly 1,500 kilometers per hour. The exact speed varies depending on latitude and the time of year, but that’s just an average. That rotation also brings the Earth around our orbit in space once every 24 hours and 8 minutes.
The rotation of the earth and day/night cycle
Like most planets, Earth spins around an axis. This axis points in a specific direction and acts as a pivot point as it rotates—it’s also called Earth’s north pole. The planet takes one day to complete one full spin on its axis, making 24 hours pass in a single day. So how does that happen if you were standing at the North Pole? As you stand there, everything appears to rotate counterclockwise. Your left hand would be pointing directly at Earth’s South Pole while your right hand would point straight up into space; if you were standing at Antarctica (Earth’s South Pole), everything would appear to rotate clockwise instead!
The rotation of the earth and seasons
It can be described as one revolution around its axis from a state of rest to another state of rest. It takes 24 hours for a complete rotation. In scientific terms, it is called diurnal motion. The earth rotates on its axis at a speed of about 1,674 km/h (1,040 mph) at the equator. This speed varies between 2,279 km/h (1,406 mph) and 1,041 km/h (646 mph) towards or away from the poles respectively. The reason why there are day and night is because in our planet's atmosphere there are two kinds of winds that drive currents that produce regions with relatively high pressure and low pressure.
The rotation of the earth and gravity
The earth is rotating, but you don’t feel it because you are rotating along with it. This may seem odd at first: why do you not feel like you are moving, when in fact your speed can be up to 1,000 miles per hour or about 1750km/h? Gravity pulls us back down to earth and keeps us traveling at approximately 1750 km/h. To put that in perspective, astronauts in orbit around earth travel at about 25,000 km/h!
The rotation of the earth and climate
The earth rotates around its axis one full time in approximately 24 hours. The length of a day depends on where you are and which direction you’re facing, as well as other factors, like magnetic fields. Although it makes sense that one side would be dark and one light when looking at earth from space (due to differing lengths of daylight), it actually isn’t that simple. Our planet doesn’t spin upright, but rather leans at an angle - 23.5 degrees - relative to its orbital plane. As such, if you were standing on an object spinning fast enough (like our little rock) and tilted over by 23.5 degrees relative to Earth's axis, your horizon would look quite different than what most people might imagine it looks like from outer space!
How fast is Earth spinning?
The Earth rotates at a speed of about 1,000 miles per hour—fast enough to make one complete revolution every 24 hours. That’s why we experience day and night. It takes sunlight about 8 minutes to reach us from our closest star (the sun) on earth’s surface. This means that if it weren’t for the earth spinning, we would only get light during daytime and darkness during nighttime!
Is it correct to say that we are standing still while our planet rotates around us?
Yes, it’s not just a matter of semantics. We are actually standing still, and our planet rotates around us.
