The Alaskan coastline adjacent to the Gulf of Alaska is experiencing similar sea-level changes to Norway, Sweden, and Finland. However, the magnitude of the sea level changes along the Alaskan coastline is much more pronounced. The changes in sea level not only reflect what is happening in Norway, Sweden, and Finland but also which other contributing factor? a. seawater is displaced from this region because it is flowing toward other regions like water sloshing in a bathtub).
b. uplift of the land due to a convergent plate boundary.
c. nearby rifting causing a deep trench/rift valley into which seawater is flowing.
d. pumping of hydrocarbons from beneath Prudhoe Bay.

b. uplift of the land due to a convergent plate boundary.

Explanation:

We are informed about The Alaskan coastline adjacent to the Gulf of Alaska is experiencing similar sea-level changes to Norway, Sweden, and Finland. However, the magnitude of the sea level changes along the Alaskan coastline is much more pronounced. The changes in sea level not only reflect what is happening in Norway, Sweden, and Finland but

uplift of the land due to a convergent plate boundary. According bto the scientist, Global mean sea level has risen with about 8–9 inches arround 1880 till now. The cause of Sea level rise can be attributed to two factors which is related to global warming, these two factors are

✓ factors as a result of the water that is added as a result of melting ice sheets as well as glaciers.

,✓ expansion of seawater as it becomes warms.

uplift of the land could be regarded as the vertical elevation of the surface of Earth as a result of natural occurrence, which could be as a result of global glaciation and is possible with convergent plate boundary which is as a result of the destruction of the crust which leads to one plates diving under another. Whenever continent converges on an ocean ridge, an increasingly thin as well as hot subducting plate is over-ride, as a result of this, there will be upliftment of leading edge of the continent as well as inland during convergence. Subduction zones is formed when plate that has thinner oceanic crust goes beneath that thicker continental crust.

The answer is C
