As the plates split apart magma rises from below the Earth’s surface to fill in the empty void. … Like any rock the plates of basaltic composition become less thick and denser as they cool. Which is the youngest rock in this strata? WebIf you took a cubic centimeter of the rock from the continental crust, it would be about 2.7 grams. A cubic centimeter from the oceanic crust, on the other hand, would weigh about three grams. While this difference in density might not seem like much, it completely changes how tectonic plates interact.

WebComparing the ages of the oceanic crust near a mid-ocean ridge shows that the crust is youngest right at the spreading center, and gets progressively older as you move away from the divergent boundary in either direction, aging approximately 1 million years for every 20-40 km from the ridge. WebThis theory was further supported by sea floor spreading, where new ocean crust was being continually created in zones in the middle of oceans, such as the mid Atlantic ridge which is moving the Eurasian plate and North American plate apart by 3cm/year.
