The type of fossil fuel that forms only from the remains of plants

The type of fossil fuel that forms only from the remains of plants is known as coal. Coal is a sedimentary rock formed from the accumulation and gradual decay of plant material over millions of years. To get this answer, one can start by understanding the process of fossil fuel formation. Fossil fuels are formed from the buried remains of ancient plants and animals that have been subjected to high pressure and temperature over millions of years. Specifically for coal, it is formed from the remains of plants that lived in marshy environments such as swamps and peat bogs. Over time, with the accumulation of plant materials and the absence of oxygen, heat and pressure transform the organic matter into coal.

Petroleum and coal form from the remains of plants.
