If subduction occurs faster than oceanic crust can be created, an ocean gets _____.
A. smaller
B. larger
C. deeper
D. shallower
I think it is smaller but I am not sure.
smaller!
I am pretty sure it's A
To determine the correct answer, let's first understand the concepts involved. Subduction is a geological process where one tectonic plate moves beneath another plate into the Earth's mantle. Oceanic crust is constantly being created at mid-ocean ridges through volcanic activity, and it moves away from the ridges over time.
Now, consider the statement: If subduction occurs faster than oceanic crust can be created, an ocean gets _____.
If subduction is happening faster than new oceanic crust is being created, it means that more crust is being consumed or destroyed at subduction zones than is being produced at mid-ocean ridges.
This implies that the ocean is essentially losing crust, which can lead to a decrease in its size. So, based on this information, the correct answer would be:
A. smaller
Therefore, your initial intuition is correct.
