The main focus of geomorphology is the study of the processes that shape the Earth's landforms and landscapes. This branch of geology examines the formation, evolution, and classification of various geological features, including mountains, valleys, rivers, and deserts. Geomorphologists analyze factors like erosion, sedimentation, and tectonic activity that contribute to landscape changes over time. Through this field, scientists gain insights into the Earth's history, its changing environments, and how human activity can impact these processes. Understanding geomorphology is pivotal in fields like environmental science, urban planning, and natural hazard assessment.
