Question

what accounts for the age difference between the younger ocean floor rocks and and the much older continental rocks> transform boundaries subduction zones there is no difference they are the same age divergence

Explanation:

Ocean - floor rocks are younger because they are constantly recycled at subduction zones. At these zones, oceanic crust is forced beneath continental or other oceanic crust. This recycling process keeps the ocean - floor rocks relatively young compared to continental rocks which are not as actively recycled. Transform boundaries mainly involve lateral movement of tectonic plates and do not account for the age difference. Divergence creates new ocean - floor crust but does not explain the age difference as well as subduction zones. And it is known that ocean - floor rocks are younger than continental rocks.

Answer:

subduction zones
