How fast does the earth spin at different longitudes

how fast does the earth spin at different longitudes

Specifically, Earth rotates faster at the Equator than it does at the poles. Earth is wider at the Equator, diffeeent to make a rotation in one hour period, equatorial regions race nearly 1, kilometers 1, miles per hour. Scientists say Earth is spinning faster than it has in decades. Because of its elliptical orbit, it is moving faster when closest and slowest when farthest, but its rotation rate is constant. At the equator, the Earth spins about twice as fast as a commercial jet can fly. Earth moves very fast. It spins rotates at a speed of about 1, miles kilometers per hour and orbits around the Sun at a speed of about 67, mileskongitudes per hour.

  • But hang on a second. If we're going to bring simple trig into this calculation, it helps to assume that the Earth is a perfect sphere — but it's not.

    You'd never know it from images like this onebut our planet is actually an oblate spheroid a sphere that's been smooshed a little bit. It's also not perfectly smooth; the radius of the Earth measured to the base of Mount Everest is smaller than it is measured to the mountain's peak. And what about the fact that a full rotation of the Earth doesn't actually take 24 hours, but roughly 23 hours and 56 minutes — wouldn't that affect our calculations, as well?

    As Kadish explains:. Because Earth is an oblate spheroid rather than a sphere, I varied the radius as earty function of latitude when calculating longitudez tangential speed. The polar radius is miles and the equatorial radius is miles; I approximated the radius at other latitudes via a linear interpolation.

    This has no visible effect on the curve, though. Topography of the Earth is equally unimportant for this level of accuracy because the difference between a mountain peak and the bottom of the ocean is trivial compared to the radius of the Earth. Gravity from Earth pulls on the closest tidal bulge, trying to keep it aligned.

    The Moon is spinning. It spins once every The moon does rotate on its axis. One rotation takes nearly as much time as one revolution around Earth. If the moon were to rotate quickly several times each longitudse or not rotate at all, Earth would be exposed to all sides of the moon i. The moon does not have atmosphere like Earth to support life.

    Moreover there is no water and suitable te for sustaining life. The gravitational pull of Moon is also very weak. Position a globe so that light from the Sun shines on it in just the same way that sunlight shines on the Earth. Follow these instructions to position your globe. Over the course of the day, compare the light on your globe to the light shown on this interactive map.

    A more detailed version of this activity can be found at Earth Learning Ideas. To track the movement of sunlight on Earth, you need a windowsill in the sun, a small mirror, and sticky notes.

    How fast does the Earth spin?

    Place the mirror on faast windowsill so that it reflects sunlight onto a wall. Write the time on a sticky note and place it in the spot of light. Have students predict where the spot of light will be in 15 minutes and mark that spot with a sticky note. While you wait to see if longiyudes prediction is right, have students discuss why they chose the spot they did.

    Use these time-lapse videos of sunrise and sunset to review what students know. In the middle of the day? In the afternoon? Why do you think it looks like it's moving fast in the video?

    Here is a link to the previous version. Preview activity. All students will be standing up and spinning in place throughout the activity with a place to view their paper Sun model.

     · This is about 24, miles (40, kilometres) per day. To calculate speed, Mr Kadish divided that distance by 23hr, 56m, 4s to reach the figure .  · Earth moves very fast. It spins (rotates) at a speed of about 1, miles ( kilometers) per hour and orbits around the Sun at a speed of about 67, miles (, kilometers) per hour. We do not feel any of this motion because these speeds are constant. Activity: Earth in the Sun Position a globe so that light from the Sun shines on it in just the same way that sunlight shines on the Earth. As the Earth spins, the boundaries between “day” and “night” will move steadily across both your globe and the Earth.

    We find that placing the Sun model on a desk and standing doees a foot behind the desk works well. If you have a lamp or bright light, you can also use this as a model for the Sun. Just remind students NOT to look directly at the bulb. If you'd like our team to reply to you, please Contact Support instead. Thanks for your feedback!
