Which of the following scenarios is most likely to result in an emergent coast?
A) global sea level rise
B) uplift associated with active margin tectonics
C) subsidence of the shoreline caused by near-shore removal of groundwater
D) the formation of a near-shore coral reef

Question

Quizplus · Accepted Answer

Emergent coastlines are typically associated with tectonic uplift, which raises the land relative to sea level. This can result from active margin tectonics, such as along the west coast of South America or the east coast of the United States, where tectonic forces are lifting up the land. While global sea level rise may cause some changes in the coastline, it would not necessarily lead to an emergent coast. Subsidence of the shoreline caused by near-shore removal of groundwater would lead to a sinking coastline, not an emergent one. The formation of a near-shore coral reef can provide some protection against erosion and may cause minor changes to the profile of the coastline, but it would not typically result in an emergent coast.
