Question

Gas and oil from the dead creatures, the gas, and oil are trapped under layers of rock

use the idea of density to explain why the gas is on top of the oil

Answer 1

Gas is on top of oil

Step-by-step explanation:

Gas is less dense ( smaller density ) than oil which is more dense. Since density is directly proportional to mass and inversely proportional to volume, gas will occupy a larger space than oil.

The larger space occupied is the space above the mixture of oil and gas, hence gas is above oil
