You have to know chemistry because you learn rock and mineral. You study earth and rock and mineral.
mineral
A mineral is any chemical compound with a constant chemical composition, which of course is the definition of a "pure substance". In earth science you might be distinguishing between "rock" and "mineral". A mineral is a pure substance. A rock is a mixture of two or more minerals in various proportions. For instance, the rock granite is made up of three minerals: quartz, feldspar and biotite (mica).
A geologist is an expert on rock and earth science, studying the composition, structure, and processes of the Earth's crust. They analyze rocks, minerals, and land formations to understand geological phenomena such as earthquakes, volcanic eruptions, and plate tectonics. Geologists play a crucial role in fields like mineral exploration, environmental protection, and natural hazard assessment.
The best way is to visit mineral occurrences and collect them yourself. Search the internet, visit local museums, or a local universities earth science department to find collecting areas near you.
