Answer 8

c. It is older near the center and younger near the continents.
because continents get pushed up or down by techtonic plates which means the water near the cusp either augments or declines which thus means that it is younger and newer
if you think about it it will take forever until the depths of the middle atlantic are pushed up which means its been that way for centuries
but like the waters surrounding a volcano; they will be new
