What Does “Geology” Really Mean?
“Geology” is the scientific study of Earth’s structure, materials, processes, and history. It includes the study of rocks, minerals, soil, landforms, and the forces shaping the planet over time.
Key traits include:
- Earth Structure: Understanding layers, crust, mantle, and core
- Processes: Volcanoes, erosion, earthquakes, and plate tectonics
- Materials: Rocks, minerals, fossils, and soils
- History: Evolution of landscapes and geological timelines
Think of geology as a way to explore Earth scientifically—how it formed, changed, and continues to evolve.
