How is oil extracted from Canadian tar sands?

A. Mountaintop removal
B. Fracking
C. Subsurface mining
D. Strip mining
E. Conventional oil wells

Answer :

C) subsurface mining. Canadian tar sands, also known as oil sands, are extracted through a process called subsurface mining, which involves removing the overburden (layers of soil and rock) to access the tar sands below

Oil is extracted from Canadian tar sands through a combination of subsurface mining and conventional oil wells. Subsurface mining involves using steam to heat the tar sands underground, making the oil easier to extract. Conventional oil wells are also used to extract oil from the tar sands, but they require more drilling and are less efficient. Fracking is not typically used in the extraction of Canadian tar sands, as it is primarily used to extract oil and gas from shale formations. Strip mining and mountaintop removal are also not commonly used in the extraction of Canadian tar sands.
Fracking and conventional oil wells are methods used for extracting oil from other types of deposits, but not tar sands. Mountaintop removal and strip mining are typically associated with coal extraction.

Final answer:

Oil is extracted from Canadian tar sands through strip mining. The process involves removing the top layer of soil and vegetation to expose the sands, which are then mixed with hot water to separate the oil.

Explanation:

Oil is extracted from Canadian tar sands through a process called strip mining. This involves removing the top layer of soil and vegetation to expose the tar sands beneath. Large shovels and trucks are then used to transport the sands to a processing facility where they are mixed with hot water to separate the oil from the sand. The extracted oil is then further processed to remove impurities and converted into usable petroleum products.
