The Earth rotates at a slower speed at the poles compared to the equator. At the poles, the rotational speed is essentially zero, so a point on the Earth's surface at the North or South Pole does not move in relation to the planet's axis of rotation.
For example, the movement of Earth around the Sun is about 30 km/sec. You decide whether you consider this fast or slow; but it is quite fast compared to speeds we are accustomed to, here on Earth.
The Earth's rotation is extremely constant, but there is a VERY SLOW trend to the rotation of the Earth getting the tiniest bit slower. But it doesn't speed up.
Major earthquakes can cause fractional changes in the Earth's rotational rate, but again, these are quite tiny.
The atmosphere rotates along with the earth. If it did not, then there would be
constant perpetual winds of about 1000 mph at the equator, and about 700 mph
at the latitude of Minneapolis.
The Earth rotates at 1040mph AT THE EQUATOR. Three feet from the North Pole your only going 9 inches per hour! A circle w/3 foot radius is 18 feet. 18 feet in 24 hours is 9 inches an hour. To see how fast YOUR head is spinning, multiply the Cosine times your latitude times 1040 for mph and cos(Lat) 1670 for km/h. In Eureka, CA (40 degrees latitude), your doin' about 800mph.

Because of the earth's tidal forces,frictional forces occur on the surface. Friction is a dissipative force so the rotational Kinetic Energy of the earth is being lost. As a result, earth spins about 1.6cm/s slower every century!! Based on some strictly amateur reading that I have done over the last couple of years, there may be forces that we don't yet fully understand that might cause the earth's axial rotation to actually increase very slightly from time to time. I'm basing this on the fact that we have recently gone through a period much longer than expected (a few years) when there was no need to add a leap second to the clock. It would take a very long time to explain the need for an occasional "leap second", and also to explain the highly counter-intuitive idea that adding leap seconds at a more or less constant rate implies a constant axial rotational velocity, and not a decreasing velocity. Again very counter-intuitively, no need for leap seconds can happen only if rotational velocity is increasing. Based on this inexplicably long period without the adding of leap seconds, it may in fact be that the rotational velocity increased by a small degree, for a while.
There used to be a few planes fast enough, but I believe that all of the SR-71's have been retired. "Sled drivers" have written about making the Sun rise in the west, as the "Blackbird" flew west across the Pacific Ocean faster than the Earth could rotate away from it. There are rumors of a new replacement for the SR-17 71 nicknamed "Aurora". It would certainly be fast enough to do so.(Darned typos!)
-- The above answer is not entirely correct. Yes, the SR-71 (not SR-17, which does not exist) could fly faster than the Earth rotates. But it is certainly not the only plane that can or could do so. Planes that are much slower than the SR-71 can fly faster than the Earth's rotation too. The Earth rotates at approximately 1000 miles per hour (Goddard Space Flight Center on Earth's rotation speed: http://imagine.gsfc.NASA.gov/docs/ask_astro/answers/970401c.html). The Concorde, a plane much slower than the SR-71, flew at an average cruising speed of Mach 2.02 or 1,549 MPH or 2,495 KPH. That is already over 500 MPH over the Earth's rotation speed. Since most military fighter planes that travel at supersonic speeds fly well in excess of the Concorde's average cruising speed, one can presume that most fighter planes, the SR-71 included, can exceed Earth's rotation speed as well (in fact, by a long shot). Mach 1 is the speed of sound, which is 767 MPH or 1,235 KPH. The SR-71 flew at speeds over Mach 3.2, which is 2,454 MPH or 3,952 KPH. That's almost 2.5 times the speed of the Earth's rotation. So planes that are much slower than the SR-71 can out-fly the Earth's rotation/sunrise/sunset. However, a conventional non-supersonic plane (which typically flies anywhere between 450 and 650 MPH). will not be able to fly faster than the Earth's rotation. But a race between the SR-71 and the sunrise or sunset is no competition! The plane will win every time by a substantial margin.
The Earth spins at a rate of about 15 degrees per hour. At the equator, the "tangent velocity" is about 1,066 miles per hour, and this speed decreases as latitude increases. At mid-latitudes in the United States - or in Australia - the velocity is between 600 and 800 miles per hour.
At either pole, the velocity is approximately zero.

How fast does the earth rotate on its axes?
The Earth rotates on its axis at a speed of about 1,000 miles per hour (1,600 kilometers per hour) at the equator. As you move towards the poles, this speed decreases.
What planet rotate as fast as earth?
Mars
Where does the earth rotate from?
It spins on its axis - which passes through the physical north & south poles.
What is it called when if the Earth did not rotate global winds would follow what path?
If the Earth did not rotate, global winds would follow a north-south path from the poles to the equator, due to the temperature difference between the poles and the equator. This wind pattern would be known as the Hadley cell circulation.
What kind of wind system would earth have if it did not rotate?
If Earth did not rotate, the wind system would be governed mainly by temperature differences between the equator and poles, leading to a simple north-south circulation pattern. Winds would blow from the poles towards the equator at the surface, and from the equator towards the poles aloft. The rotational effects that give rise to the complex global wind patterns we observe today would be absent.
If earth did not rotate could you define the celestial poles and celestial equator?
If Earth did not rotate, the celestial poles would align with the geographic poles, and the celestial equator would align with Earth's equator. The celestial poles are points in the sky that the Earth's axis points towards, and the celestial equator is an imaginary line in the sky directly above the Earth's equator. Without Earth's rotation, these references would be fixed in the sky.
How fast does the earth rotate on its axes?
The Earth rotates on its axis at a speed of about 1,000 miles per hour (1,600 kilometers per hour) at the equator. As you move towards the poles, this speed decreases.

How slow or fast does earth rotate?
The planet Earth rotates on its axis exactly once per day.
How fast does the Earth rotate in feet per second?
About 1,076.03 feet per second.
How fast does North America rotate?
the Earth revolves about 23 miles per sec.
How would the wind blow if the earth did not rotate?
If the Earth did not rotate, the winds would flow from the poles towards the equator in a straight line due to the temperature differences between the poles and the equator. There would be no Coriolis effect to influence the direction of the wind, resulting in simpler and more predictable wind patterns.
If Earth did not rotate could you still define the celestial poles and celestial equator?
You can't - those things wouldn't exist. Both are defined in terms of Earth's rotation.
How long does the sun rotate?
The sun's rotation period varies depending on the latitude, with the equator taking about 25 days to rotate once, and the poles taking around 35 days.
How fast does the earth rotate on the equator?
Almost exactly 1 rotation per 24 hours.
