* Potential Energy: Rocks can store potential energy due to their position. For example, a rock perched high on a cliff has potential energy because of its height. If the rock falls, that potential energy is converted into kinetic energy (energy of motion).
* Chemical Energy: Some rocks contain minerals with chemical energy. For example, coal is made of fossilized plants and contains chemical energy that can be released by burning.
* Geothermal Energy: Rocks deep within the Earth hold geothermal energy. This is heat energy generated from the Earth's core. This energy can be tapped for power plants.
* Elastic Potential Energy: Some rocks, like those in fault zones, can store elastic potential energy when they are stressed. This energy can be released in earthquakes.
Important Note: While rocks can contain and store energy, they don't store it in the same way as batteries. Rocks don't have a charge or an electrical current like a battery. Instead, the energy stored in rocks is related to their position, composition, or internal stress.
