Explanation

A thin layer of oil on water is called oil slick. Oil slicks float on oceans and seas, covering them with a thick film of crude or refined petroleum oil. When freight ships carrying thousands of tons of fuel crash, malfunction, or encounter harsh weather, they spill enormous amounts of oil into the water.
