Question

Wally is a planetologist in the future. He discovers a planet similar to Earth that has two major oceans. Ocean A is
very large and looks like it has baseball stitches down its center. Ocean B is very small and has volcanoes all along
one side. Wally needs to predict what the planet will look like far into the future. Which prediction would most likely
come true?
Ocean A will shrink, and Ocean B will get bigger.
Ocean A will disappear, and Ocean B will remain the same.
Ocean A will get bigger, and Ocean B will shrink.
Both Ocean A and Ocean B will remain the same.

Answer 1

Answer:

 Option (C)

Explanation:

The divergence of two oceanic plates leads to the expansion of the ocean. The mid-oceanic ridge occurs along the divergent plate boundary, where the magma comes out to the surface of the ocean floor and solidifies. This region experiences more stretching as a result of which the sea floor near the mid oceanic ridge appears like the baseball stitches. This oceans in due course of time becomes large because of the continuous expansion. For example, the Atlantic ocean is rapidly expanding.

On the other hand, the oceans also gets shrink because of the convergence of oceanic and continental plates and convergence of two oceanic plates. They are often marked by the presence of active volcanisms in its adjacent plate. These oceans due to the continuous convergence, leads to the shrinkage of oceans. For example, the Pacific ocean.

Thus, the ocean A will become larger and Ocean B will shrink.

Hence, the correct answer is option (C).
