Explanation:
Spreading center volcanism occurs at the site of mid-oceanic ridges, where two plates diverage from one another. As the plates are pulled apart, hot ashtenophere rise upward to fill voids of the extended lithosphere.
B.the windward side of a mountain range tends to to wetter than the forward side
Oceanic crust is denser than continental crust. At a subduction zone, the oceanic crust usually sinks into the mantle beneath lighter continental crust. ... If the same kind of crust collides, such as continent-continent, the plates may crash together without subducting and crumple together like crashing cars.
