Geophysical processes refer to the natural phenomena that shape the Earth's physical features and environment. These processes include activities such as volcanism, earthquakes, and plate tectonics, which are driven by the movement of the Earth's internal materials. They play a crucial role in forming mountains, valleys, and other geological structures. Additionally, geophysical processes influence the Earth's climate and ecosystems. For example, erosion and sedimentation affect landforms and habitats, while ocean currents and atmospheric circulation impact weather patterns. Understanding these processes helps scientists predict natural events and manage resources effectively.
