Each of these contain specific organisms that are affected by the processes and hazards of coastal change.
- Coast | Marine Life, Geography & Ecology | BritannicaCoast, broad area of land that borders the sea. A brief treatment of coasts follows. For full treatment, see coastal landforms. The coastlines of the world’s continents measure about 312,000 km (193,000 miles). They have undergone shifts in position over geologic time because of substantial changes.
- 21.3: Types of Coasts - Geosciences LibreTextsSubmerged coasts form when river mouths are flooded due to rising sea level or subsidence of land. A drop in sea level or rise in the land surface creates an emergent coast. Depositional coasts have abundant depositional features like deltas, bars, spits and reefs where new land has been built.
- 21.2: Coastal Landforms and Processes - Geosciences LibreTextsUniversity of Wisconsin-Stevens Point via The Physical Environment. A coast or the coastal zone is a dynamic region where land is sculpted and shaped by wave action and currents. Barring the effects of tectonic uplift and sea level change, erosion is the dominate geomorphic process acting on coasts.
- Coast - WikipediaA coast – also called the coastline, shoreline, or seashore – is the land next to the sea or the line that forms the boundary between the land and the ocean or a lake. [1][2] Coasts are influenced by the topography of the surrounding landscape, as well as by water induced erosion, such as waves.
