fossils sediments igneous rock metamorphic rock
I gave my students this multiple choice 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?

Only one answer is correct among these 4 choices:
- fossils
- sediments
- igneous rock
- metamorphic rock

Could you tell me which one is correct?

metamorphic rock
