Answers

Fossil fuels are simply solar energy stored in a secondary form. The original energy from the Sun is captured through photosynthesis and stored in chemical bonds as plants grow. This energy is then released millions of years later after these plants have transformed into fossil fuels.

Fuels, including fossil fuels, are energy sources. Fossil fuels are powered by solar energy, which also powers photosynthesis, which transforms carbon dioxide and water into the fundamental constituents of prehistoric plants and animals.
