do all parts of earth rotate at the same rate? explain?

Answer 1

All parts of the earth rotate at one rotation per day. So in that sense, yes, they rotate at the same rate.

However, the farther you are from the rotational axis, the farther you have to travel to make a full rotation, so the faster you go. At the equator, you have to travel at about 1037 MPH in order to make a full rotation in one day. 1 foot away from the rotational axis, and you have to travel at just 0.000045 MPH to make a full rotation (if my math is correct).

Depends on your perspective I guess.

Answer 2

If by rate you mean rotation rate like radians/sec, then in general no.

Well, the tides move back and forth. So when a certain quantity of water is moving east. that water is going faster than the rotation rate, radian/sec (or RPM or revolutions per day). But that's only temporary.

Answer 3

Obviously the surface of the earth rotates as a solid piece, but at the equator you're rotating at 1000 miles per hour and at the poles you're rotating at one revolution per day. Kind of cool.
