Question

what is oil slick?How is it cause
​

Answer 1

Answer:

Oil floats on saltwater (the ocean) and usually floats on freshwater (rivers and lakes). Very heavy oil can sometimes sink in freshwater, but this happens very rarely. Oil usually spreads out rapidly across the water surface to form a thin layer that we call an oil slick.

Answer 2

Answer:

Oil usually spreads out rapidly across the water surface to form a thin layer that we call an oil slick. As the oil continues spreading, the layer becomes thinner and thinner, finally becoming a very thin layer called a sheen, which often looks like a rainbow.
