At a regional level,shorelines on a tectonically passive margin commonly have
A) sea cliffs.

Question

Quizplus · Accepted Answer

Tectonically passive margins are characterized by relatively subdued geological activity, with little or no volcanic or seismic activity. This often results in extensive deposits of sediment along the shoreline, leading to the formation of wide sandy beaches. Therefore, the best choice is D - extensive sandy beaches. The other options are less likely to occur on tectonically passive margins; sea cliffs are more common on tectonically active coasts, rocky shorelines can occur on any type of margin, narrow continental shelves are more typical of active margins, and little coastal erosion is not necessarily a characteristic of passive margins.
