Describe the process by which petroleum is extracted from tar sands.
a) Petroleum is extracted from tar sands through a process called fracking, which involves injecting high-pressure fluid into the ground to fracture the rock and release the oil.
b) Petroleum is extracted from tar sands by heating the sands to separate the oil from the sand particles, then pumping the oil to the surface.
c) Petroleum is extracted from tar sands by drilling wells into the sand deposits and using pumps to bring the oil to the surface.
d) Petroleum is extracted from tar sands by evaporating the water content, leaving behind the oil for collection.
