The primary focus of geology is the study of the Earth, including its composition, structure, processes, and history. Geologists explore various aspects such as rocks, minerals, fossils, and the forces that shape the Earth over time, including tectonic movements, erosion, and sedimentation. This field aims to understand the Earth's formation and development, as well as the processes that affect its surface and interior, such as earthquakes and volcanic activity. Geology also plays a crucial role in natural resource management, environmental protection, and understanding climate change, making it a vital scientific discipline for addressing global challenges.
