Question

Quizplus · Accepted Answer

The Atlantic and Gulf coasts of the United States are mostly characterized by lowland beaches and barrier islands, which are formed by the action of deposition and erosion of waves and currents. There are some rocky cliffs in certain parts of the coasts, but they are not the predominant feature. Coral reefs are more common in tropical regions near the equator. Tectonic coasts are associated with active geological processes, such as oceanic trenches, volcanic islands, or uplifted sedimentary rocks, and they are not widespread in the US coastlines. Wave-cut coasts are formed by the mechanical action of waves cutting into rocky shorelines and creating distinct landforms such as sea cliffs, sea stacks, or wave-cut platforms, but again, this is not the prevalent feature of the US coasts. Therefore, option B is the most suitable answer.
