Would you expect to find a well-preserved dinosaur bone in a metamorphic rock like schist? Explain.
No; the heat, pressure, and chemical changes that form metamorphic rocks likely would destroy the dinosaur bone.

Model that describes how all rocks are subject to constant change.
Explain how the mineral quartz could be in both an igneous rock and a sedimentary rock.
Quartz forms in igneous rocks as magma cools. If such a rock is weathered, eroded, and deposited as sediment, the quartz can be cemented and compacted into sedimentary rock.
How is it possible to find pieces of gneiss, granite, and basalt in a single rock?
If gneiss, granite, and basalt were all exposed to weathering and erosion, pieces of all three could be moved and deposited together to form a sedimentary rock.
Why must ores be processed after they are mined?
