Question

Describe what an oil sand is and explain the advantages and disadvantages associated with its use and extraction

Answer 1

Oil sands are a mixture of sand, water, clay and bitumen. Bitumen is oil that is too heavy or thick to flow or be pumped without being diluted or heated. At 10° C/50° F, bitumen is hard as a hockey puck. Some bitumen is found within 70 metres (200 feet) of the surface, but the majority is deeper underground.
