Which type of scientist studies rocks, minerals, fossils, and Earth's history?

• A. Biologist
• B. Meteorologist
• C. Astronomer
• D. Geologist

Answer: (D)

Geology is the science that studies rocks, minerals, fossils, and Earth's history. A geologist examines the materials that make up our planet and what they reveal about how Earth formed and changed over time. For example, sedimentary rocks form in layers that often contain fossils, teaching us about ancient environments and life. By looking at rock types, layering, and fossil fossils, geologists piece together the story of Earth’s past, including processes like erosion, deposition, and tectonic plate movements. The other sciences focus on different topics—biology on living organisms, meteorology on weather, and astronomy on space—so geology uniquely fits the description of studying Earth materials and its history.
