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.

Explanation:

The "baseball - stitches" appearance in Ocean A suggests a mid - ocean ridge, which is a divergent plate boundary where new crust is formed, causing the ocean to expand. The presence of volcanoes along one side of Ocean B indicates a convergent plate boundary where one plate is subducting under another, causing the ocean to shrink over time.

Answer:

Ocean A will get bigger, and Ocean B will shrink.
