The answer to your question would more than likely be chemical energy, natural gas, and chemical energy. but I don't know what grade your in I'm in eighth if your below I know the answer. I'm pretty sure I had a question exactly like this last year but that was last year so if it's wrong sorry. I looked it up on Google to make sure

Answer:
2. Volcanoes
Explanation:
The interior of some planets (e.g earth) contains some hot flowing fluids called lava which has a very high thermal energy. The lava as a means of escaping the confinement within the planet, burst out by creating an opening through the ground to the surface of the planet to release the energy (lava).
This process in which the energy is released to the surface of the planet is termed volcanic eruptions. Which occurs majorly in some susceptible regions of the earth.
The openings in the ground that release energy from deep inside the planet is thus called volcanoes.
