so uh,uh, frankly, the only good explanation for why we see this pattern, why we see this newer land here and then as we go further and further up the hawaiian island chain we see older and older land actually if we keep going, if we keep going we have the leeward islands over here as we, as we keep measuring the rock on the leeward island as we get older and older as you go to the northwest and if you even look at what's below the ocean. this is the big island of hawaii these are the main hawaiian islands,these are the leeward islands but you see even beyond that submersed under the pacific ocean, you continue to see a chain of islands.
