Uluru is listed as the worlds largest rock. Is it truly an “individual stone” or is it attached to bed rock? How was it formed?

Its not a sole rock sitting on top of 'earth' as such. Its a sedimentary layer that has been uplifted by 90degrees and this end pokes out. One end of the rock used to be 'down' and the other was 'up' and much newer. Its believed that the rock layer curves down 6-7km and then re-emerges some way away as The Olgas, another interesting rock formation.
