Eustatic Change in addition to Submergent vs. Emergent Coastlines during ice ages sea level sinks as ocean water compresses in addition to more water is tied up in glaciers. During interglacial periods sea level rises, flooding many as long as mer river valleys creating bays in addition to estuaries. In areas with rapid tectonic uplift emergent cliffs common in addition to bays rare. Submergent Coastlines Sea level rise inundated many coastal valleys creating bays in addition to estuaries. These coasts are referred to as ria coastlines. Estuary – An arm of the sea that extends inl in addition to to meet the mouth of a river. Emergent Coastlines Tectonic as long as ces lift coastlines faster than sea-level rises. Dramatic cliffs in addition to marine terraces tower above the sea.
COASTAL FLUVIAL PROCESSES/LANDFORMS Coastal Erosion – dependent on wave size, angle, in addition to frequency. Focused where waves contact coast. Headl in addition to s, sea cliffs, bluffs, sea stacks, natural bridges Beach Erosion Coastal Transportation – wave action creates strong currents parallel to shore. Large waves move beach s in addition to offshore. Small waves push it back on shore. Longshore current Coastal Deposition where wave action is reduced, beaches in addition to dunes as long as m. beaches dunes s in addition to spits
