A rock on top of a mountain contains POTENTIAL ENERGY. The reason for this is that potential energy means that it has the potential to become another form of energy, like kinetic. If a rock is sitting on a mountain, it's not moving. Once it moves, it has KINETIC ENERGY. For example; I'm sitting on top of a mountain.
Oil shale is a rock that contains significant amounts of organic material in the form of kerogen. Up to 1/3 of the rock can be solid kerogen. Liquid and gaseous hydrocarbons can be extracted from oil shale but the rock must be heated and/or treated with solvents.lthough drilling can extract large amounts of oil and natural gas from the reservoir rock, much of it remains trapped within the shale. This oil and gas is very difficult to remove because it is trapped within tiny pore spaces or adsorbed onto clay mineral particles that make-up the shale.
