100 What are the layers of the Earth? Crust, mantle, outer and inner core.	100 What is a rough jagged flow of a mafic lava? aa	100 What are the 7 major tectonic plates? North American, South American, Eurasian, Indo-Australian, Antarctic, African, Pacific	100 What are igneous rocks? Crystallized magma.	100 What plate boundaries produce magma? Divergent and Convergent.
200 What is mineral hardness? Resistance to scratching.	200 What is a smooth ropy flow of a mafic lava? pahoehoe	100 What are three plate tectonic boundaries? Convergent, divergent, Transform Fault	200 What is gabbro? A mafic, phaneritic igneous rock.	200 What process produces magma at a hot spot or divergent plate boundary? Decompression melting.
300 How does magma viscosity control the violence of eruption? Higher viscosity = higher explosive low viscosity = fluid flow	300 What volcano would you expect to find above a subduction zone?
