Remember that appearance does not equate to composition. Relatively fine-grained material of all types on any body will look quite similar, but it originated via a variety of processes. For example, the 'sand dunes' of Titan would quickly melt or sublimate under terrestrial conditions. wink.gif

It does, and does rotate faster near the equator than at the poles. Speed can be estimated from sun spot motion. See, for instance this wikipedia article on "Solar rotation"
