Petrologists are scientists who study rocks and the processes that form them. They analyze the mineral composition, texture, and structure of rocks to understand their origins and evolution. This field of study is essential for understanding Earth's history and the processes that shape its surface. In addition to studying igneous, sedimentary, and metamorphic rocks, petrologists often work with geologists and geochemists to explore natural resources like oil, gas, and minerals. Their research can also provide insights into natural hazards, such as volcanic eruptions and earthquakes, helping to mitigate risks to communities.
