- The continental crust mainly is made of granite
- Granite is a kind of igneous rock
- So, the continental crust is mainly made of igneous rock

- Basalt is a kind of igneous rock
- The oceanic crust mainly is made of basalt
- Hence, 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
- So, continental and oceanic crust are mainly made of igneous rock

- Oceanic crust is a kind of crust
- Continental crust is a kind of crust
- Therefore, 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
- Hence, 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
- So, 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
- Therefore, 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
- Therefore, 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
- So, 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
- Intense can mean extreme
- Hence, 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
- Therefore, two tectonic plates pushing toward each other changes the earth's crust material into metamorphic rock

Hence, two tectonic plates pushing toward each other changes the earth's crust material into metamorphic rock
Question
Two tectonic plates pushing toward each other cause intense heat and pressure in Earth's crust. Into which will crust material be changed by heat and pressure?
