Petros, meaning "stone" in Greek, is often associated with strength and stability. In various cultures, stones symbolize endurance and resilience, representing the idea of being grounded and unyielding. The term is also linked to the biblical figure Peter, one of Jesus' apostles, whose name means "rock," signifying his foundational role in the early Christian church. In geology, stones are naturally occurring solid aggregates of minerals or mineraloid matter. They are classified into three main types: igneous, sedimentary, and metamorphic. Each type forms through different geological processes, contributing to the Earth's diverse landscape and providing essential resources for construction and art.
