Geology is the scientific study of the Earth’s structure, composition, processes, and history. It examines everything from the formation of rocks and minerals to the movement of tectonic plates and the shaping of landscapes by erosion, earthquakes, and volcanic activity. Geologists also study Earth’s deep past through fossils and rock layers, helping to reconstruct ancient climates and ecosystems. This field plays a crucial role in understanding natural hazards, locating natural resources, and addressing environmental challenges. Ongoing research in geology not only deepens our knowledge of Earth’s past but also informs how we plan for its future.
