DIFFERENT PARTS OF THE SUN ROTATE AT DIFFERENT SPEEDS AROUND IT'S AXIS


The Sun's Magnetism

     The rotation of the Sun around its axis, therefore, does not by itself contribute to its magnetism. What is important in this case is that the Sun does not rotate like a solid ball. Its equator has a shorter rotation period than higher latitudes-- about 25 days for the equator, 27 days for latitude 40 degrees (the Earth meanwhile moves some distance around the Sun, so from here the period seems to be 27 and 29 days). If Earth rotated that way, Florida (for instance) would soon pull away from the rest of the US, into the Atlantic Ocean. Such an uneven motion, deforming the surface, can drive a dynamo, and in the Sun's case, it is indeed believed to be the source of sunspot magnetism
END PARTIAL QUOTE FROM:
dynamo effect.
THE POINT ABOUT FLORIDA WINDING UP IN THE MIDDLE OF THE ATLANTIC IF EARTH DID THIS MAKES SENSE.

SO, MAYBE THE BEST WAY TO THINK ABOUT THIS IS TO THINK OF THE SUN LIKE IT WAS LIQUID (I SUPPOSE PLASMA IN THE SUN MIGHT HAVE SOME OF THE SAME PROPERTIES AS A LIQUID WOULD HERE ON EARTH).

SO, AS THE SUN TURNS THE VOLUME OF PLASMA IS GREATER AT THE EQUATOR. BUT IF THIS IS TRUE WHY IS THE EQUATOR ROTATING FASTER THAN FURTHER NORTH OR SOUTH ON THE SUN AS FAR AS A COMPLETE ROTATION OF PLASMA CONCERNED? 

I'M TRYING TO FIND THE LOGIC HERE BUT SOMEHOW IT IS MISSING ME. 

THE ONLY LOGIC I CAN COME UP WITH HERE IS THERE IS MORE FRICTION AT THE EQUATOR SO THE PLASMA IS THINNER BECAUSE OF HEAT CAUSED BY THE FRICTION AND CAN THEREFORE SPIN FASTER AT THE EQUATOR IN ROTATING AROUND IT'S AXIS.
