They are called petroleum.
Most rockets today use liquid oxygen and liquid hydrogen as fuel, not fossil fuels. These fuels react to produce water vapor and can be considered eco-friendly compared to fossil fuels. However, some rockets still use a combination of liquid oxygen and kerosene as fuel, which is a fossil fuel.
Crude oil
Fossil fuels.
Some fossil fuels are liquid (oil) some are solid (coal) and some are gas (natural gas)
Fossil fuels that can be obtained using current technology are called proven reserves.
Liquid fossil fuels are hydrocarbon-based fuels that are in a liquid state at room temperature and pressure. Examples include gasoline, diesel, and kerosene, which are derived from the decomposition of organic matter over millions of years. These fuels are commonly used to power vehicles, generate electricity, and heat buildings.
