Answer: Hi there,
Tar Sands: Used more commonly than oil sands. It helps workers make manmade roads. This was introduced around the 1800s. Although it is quite similar to Oil Sands. The U.S uses this method to create roads instead of oil sands. They are mixed the same way as oil sands but these can produce gasoline.
Oil Sands: Seems more accurate than tar, they are mixed with water, clay, and sand. It forms bitumen which is created by the following items I mentioned which make the oil sands very dense because of what else they put in there (petroleum). It is very thick compared to tar sands. They are most important in the Candian economy.
Hope this helped :)
