Answer

The correct answer is **a. nuclear reactions; chemical**.Here's why:* **Geothermal energy (the heat beneath the ground) primarily comes from nuclear reactions.** These reactions occur within the Earth's core, where radioactive elements like uranium and thorium decay, releasing immense amounts of heat.* **Fossil fuels store energy in the form of chemical bonds.** These fuels (coal, oil, and natural gas) are formed from the remains of ancient plants and animals. The energy stored within them is released through chemical reactions, such as combustion (burning).
