Coastal geology is the study of the landforms and processes along coastlines. It examines how waves, tides, and currents shape the shore, creating features like beaches, cliffs, and estuaries. This field also looks at sediment transport, which is the movement of sand and other materials along the coast. Understanding coastal geology is essential for managing coastal environments and addressing issues like erosion and habitat loss. It involves analyzing the impact of human activities, such as construction and pollution, on coastal ecosystems. Coastal geology is crucial for protecting areas like wetlands and marine habitats from degradation.
