GENERAL GEOLOGY

Detailed explanation-1: -Oil is originally found as a solid material between layers of sedimentary rock, like shale. This material is heated in order to produce the thick oil that can be used to make gasoline. Natural gas is usually found in pockets above oil deposits. It can also be found in sedimentary rock layers that don’t contain oil.

Detailed explanation-2: -It is commonly noted that petroleum occurs almost exclusively within sedimentary rocks (sandstones, limestones, and claystones). Petroleum is seldom found in igneous or metamorphic rocks. Thus petroleum geology is very largely concerned with the study of sedimentary rocks.

Detailed explanation-3: -Fossil fuel is a generic term for non-renewable energy sources such as coal, coal products, natural gas, derived gas, crude oil, petroleum products and non-renewable wastes. These fuels originate from plants and animals that existed in the geological past (for example, millions of years ago).

Detailed explanation-4: -Coal is a type of sedimentary rock formed from the remains of plants. Coal is used as a fuel for multiple reaons: Electricity generation, Steel generation.

Detailed explanation-5: -All oil and much natural gas are created by deep burial and heating of organic matter contained within sedimentary rocks.
