Why does oceanic crust subduct under continental crust when the two converge?
Oceanic crust subducts under continental crusts because they have the same density.
Oceanic crust subducts under continental crusts because oceanic crust is more dense than continental crust.
Oceanic crust subducts under continental crusts because oceanic crust is less dense than continental crust.

How does fossil evidence support Wegener’s hypothesis of continental drift?
Similar fossils found on far apart landmasses suggest that the continents were once a single land mass.
