How does the age of the seafloor affect sea level?
What will be an ideal response?
If the seafloor is mostly young and warm, then isostasy results in the young crust riding high in the asthenosphere. This results in shallow oceans and a higher sea level. If the seafloor is mostly older dense oceanic crust, then the oceans will be deeper and sea level will be lower.
