Example 1

When two tectonic plates collide, oceanic crust usually subducts beneath continental crust because oceanic crust is primarily composed of igneous rock that has
(1) low density and is mafic
(2) low density and is felsic
(3) high density and is mafic
(4) high density and is felsic

ESRT p. 10 basaltic ocean crust is more dense. Basalic = mafic on right side of igneous table on ESRT p. 6. (3)
