Document Summary
In warm climates, one of characteristics of coastlines are coral reefs - corals are precipitates of calcium carbonate (calcite) Coral reefs may build on volcanic islands - initially reefs grow around edges of volcano. As volcano sinks reef continues to grow upward (barrier reef) (fringing reef) Coral reefs build on volcanic islands - as volcano (on moving lithospheric plate) continues to sink, reef continues to grow upward when volcano is below ocean surface reef is called an atoll. One type of coastlines are those dominated by depositional processes (sediment rich. Delaware shoreline is example of sediment rich coastline to mainland shore. Another type of coastlines are those dominated by erosional processes (sediment poor. Wave cut platform- nearly horizontal surface extending from beneath wave cut coastlines) cliff toward ocean. Sea arch- arch (hollowed out area) formed in headland by wave erosion. Semi-enclosed coastal bodies of water that have free connection with ocean and have.
