The energy that comes in many forms and is hard like a rock refers to potential energy, particularly in the context of geological formations. For instance, rock formations can store energy in the form of gravitational potential energy due to their elevation and mass. Additionally, energy can be stored in fossil fuels, which are derived from ancient organic matter that has hardened over time. This energy can be transformed into various usable forms, such as thermal or kinetic energy, when extracted and utilized.
Minerals can come in a variety of forms and are naturally occurring solids that have a characteristic crystalline structure. Minerals like quartz and diamond are examples of hard minerals that can be mistaken for rocks due to their physical properties.
