Solution

The correct options are
A Oil formed the top layer of ocean water
B Oxygen supply to marine organisms was cut off
During oil spills, oil covers the topmost layer of ocean water since the density of oil is less than water. Also, oil and water are immiscible. This hampers the oxygen supply of underwater organisms (marine biodiversity) and is a major cause of water pollution.

2) It settles on top of water making a separate layer.

What is the reason for these two phenomena? Mention the property being exhibited by the oil. [3 MARKS]
