* They are all composed of minerals. Minerals are naturally occurring, solid substances with a definite chemical composition and crystal structure.
* They are all part of the rock cycle. The rock cycle is a continuous process where rocks transform from one type to another over time due to various geological processes.
* They can all be found in different parts of the Earth. While some rock types are more common in specific locations, all three groups can be found in various geological settings.
* They are all essential to the Earth's history and the environment. Each rock type provides unique insights into Earth's past and plays a role in shaping the planet's surface and ecosystems.
Essentially, although they have different origins and characteristics, the three major rock groups are interconnected and fundamental components of the Earth's geology.
