Which energy source is the result of tiny sea creatures being compressed over million of years?

Extreme pressure in the sea is the energy source that resulted in compression of tiny sea creatures into fossils, over millions of years. These creatures got buried under the ocean or river sediments, and the pressure caused their compression, leading to the formation of oil and natural gas.

Explanation:

we know that, volume of a rectangular prism is given by :

✿   {length × width × height}

given : the length of rectangular prism = 5.5

given : the width of rectangular prism = 6

given : the height of rectangular prism = 3

⇒ the volume of given rectangular prism = {5.5 × 6 × 3}

⇒ the volume of given rectangular prism = 99
