sentences: the continental crust mainly is made of granite & the continental crust mainly is made of granite1 ->  the continental crust is mainly made of igneous rock  basalt is a kind of igneous rock & the oceanic crust mainly is made of basalt ->  the oceanic crust is mainly made of igneous rock  the continental crust is mainly made of igneous rock & the oceanic crust is mainly made of igneous rock ->  continental and oceanic crust are mainly made of igneous rock  the continental crust mainly is made of granite0 & continental crust is a kind of crust ->  continental and oceanic crust are kinds of crust  the crust is made of different kinds of crust & the crust is a layer of the earth ->  the earth's crust is made of different kinds of crust  continental and oceanic crust are kinds of crust & the earth's crust is made of different kinds of crust ->  the earth's crust is made of continental and oceanic crust  continental and oceanic crust are mainly made of igneous rock & the earth's crust is made of continental and oceanic crust ->  the earth's crust is mainly made of igneous rock  the earth's crust is mainly made of igneous rock & rock is a kind of material ->  the material of earth's crust is mainly igneous rock  the material of earth's crust is mainly igneous rock & exposure to extreme heat and pressure changes igneous rock into metamorphic rock ->  exposure to extreme heat and pressure changes the material of earth's crust into metamorphic rock  exposure to extreme heat and pressure changes the material of earth's crust into metamorphic rock & the continental crust mainly is made of granite2 -> the continental crust is mainly made of igneous rock0: exposure to intense heat and pressure changes the material of earth's crust into metamorphic rock  the continental crust is mainly made of igneous rock0 & two tectonic plates pushing toward each other cause intense heat and pressure in earth's crust -> two tectonic plates pushing toward each other changes the earth's crust material into metamorphic rock
