Final answer:
Emerged coastlines possess features such as raised beaches, sea cliffs, and marine terraces, indicating that the correct answer is All of the above.
Step-by-step explanation:
Features of emerged coastlines include a variety of geological structures that have formed due to the lowering of sea levels or the rising of the land. Some key features are:
- Raised beaches: These are former beach areas that are now above the current sea level due to an uplift of the coastline or a drop in sea level.
- Sea cliffs: Vertical or steep slopes on the coast that are formed primarily by the erosive processes of waves and result from the coastline being lifted out of the reach of sea action.
- Marine terraces: Flat platforms often found bordering a sea cliff, which are remnants of former coastlines, typically created by wave erosion when the land was at a lower level.
Therefore, the correct response to the student's question regarding the features of emerged coastlines is D. All of the above.
