What are oil sands?



  1. 0 Votes

    Oil sands or tar sands (not the same thing as tar you see on the roads, that’s derived from coal) are a mixture of sand, clay and a really thick, soupy form of oil called Bitumen. They’re found as ground deposits mainly in Canada and Venezuala.

    It is not correct that tar (asphalt) on roads is made from coal. Some used to be, and some maybe still is. But by far most asphalt is derived from petroleum. Some oil refineries are geared specifically to process the heavy oils that best yield asphalt.
