John Tuzo Wilson developed crucial concepts that related to plate tectonics in 1963.
He asserted that the Hawaiian, and other island chains, may have formed due to movement of a plate over a "hot spot" in the Earth's mantle.
[Note: A __Hotspot___ is an area of abnormally intense active volcanism.]
He also argued that there must be a third type of plate boundary to connect ridges and trenches- which are called transform faults. These allowed for plates to slide past one another without oceanic crust being created or destroyed.
<span>By the given data the following conclusion is best supported: The oceanographer is is traveling toward a mid ocean ridge. At the mid-ocean ridge network crust is created. So as the oceanographer moves toward it, it becomes progressively younger. </span>
