Explanation:
Answer is A) Plateau of Arabia
The correct answer is A) water and chemicals are used to flush oil out or the rock where it is later separated from the water.
The statement that best describes how oil is extracted from the sands is "water and chemicals are used to flush oil out or the rock where it is later separated from the water."
First, shovel machines scoop out sand. Trucks take the sand, bitumen, and water to the processing facility to mix it with hot water and shaken up to divide the bitumen that is skimmed off and is diluted with chemicals to send it through pipelines. It can be diluted using light crude or natural gas. Another extraction process is Steam Extraction when oil is very deep in the ground.
The other options of the question were B) small explosions in the ground release the oil from the sands. C) the sands are melted, releasing oil. D) oil rings pump the oil from sand reservoirs.
