geological specimens

Geological specimens are natural pieces of Earth's materials, such as rocks, minerals, or fossils, collected for study or display. They reveal the composition, structure, and history of our planet, helping scientists understand processes like volcanic activity, erosion, or past life. These specimens vary widely—from a shiny mineral crystal to a layered sedimentary rock—each providing insights into Earth's geological past and ongoing changes. They are essential for research, education, and appreciating the planet’s dynamic nature.
