Although the waters are rising in the ocean today and are submerging our coastlines, there are areas of coastline that are uplifting faster than the sea is rising. these coastlines are called:

a. emergent coastlines
b. estuary coastlines
c. submergent coastlines
d. glacier coastlines

a. Emergent coastlines

Explanation:

The emergent coastlines are the coastlines that are lifting further up from the sea level. This can be either by fall of the sea levels, or by isostatic rebound. Since in the present we do not have fall of the sea levels, but the opposite, rise of the sea levels, the only way that a coastline can be emergent is by isostatic rebound. The isostatic rebound occurs at places that were once under thick ice sheet. The ice sheets put a lot of weight on them and pressed them lower, but as the ice sheets have melted, the weight is there no more, so the land is lifting up again, causing the coastline to rise quickly than the rise of the sea level. As this process happens, what was once a beach comes to be more of a cliff feature, while the cliffs have gone further away from the sea and there are new beaches that are forming below them at the places that were once covered with water. This process can easily be seen in the present on the western Scottish coastline.

a characteristic is a deep cut in the earth or left over rock aka till.
