Why are andesitic and granitic rocks confined to the continents and ocean margins but absent from deep ocean basins?
The igneous rock underlying the deep ocean basins is basaltic, as its source material comes from the asthenosphere. Andesitic igneous rock is formed at colliding plate margins, where subducting oceanic crust is partially melted and undergoes differentiation as it rises through the continental crust. Granitic rock is less dense than oceanic crust and composes the continents.
What process is responsible for moving rock materials from the continents into the ocean basins?
Erosion.
Why are continents older than ocean basins?
well continets were created by god
Ocean ridges generally are located where?
At spreading centers.
Are the ocean basins in the southern hemisphere influenced by wind belts?
Yes. Wind Belts, The Coriolis Effect, and the Position of the Continents all influence the ocean basins patterns
