Πέτρος, which translates to "Rock" in English, is a name often associated with strength and stability. In various cultures, it symbolizes a solid foundation and reliability. The term is also linked to the biblical figure Πέτρος, one of the twelve apostles of Ιησούς, who is considered a key figure in Christianity. In geology, a rock is a naturally occurring solid mass composed of one or more minerals or mineraloids. Rocks are classified into three main types: Igneous, Sedimentary, and Metamorphic. Each type forms through different processes, contributing to the Earth's structure and landscape.
