What are the rocks that makes up the continental and oceanic crusts? what minerals are they made up of?
Continental - granite - is made up of quartz, biotite, and pink feldspar Oceanic - basalt - is made up of olivine, pink feldspar, and white feldspar

What are the oceanic ridges?
They are long chains of underwater mountains (eureka page 316)
200
which layer of the earth contains the asthenosphere?
the upper mantle
300
What is the difference between a rock and a mineral?
Rocks are a heterogeneous mixture made up of various minerals
300

what are the 3 basic movements two plate tectonics to eachother?
They either 1. approach eachother 2. draw apart from eachother or 3. slide against eachother

Compare the earth to an egg,
earths crust = egg's crust mantle = white stuff (apparently called albumen) core = yolk
500
What are the phases of the rock cycle?
igneous metamorphic sedimentary rock-----> sediment (weathering and erosion) sediment -------------> sedimentary rock (compacting) sedimentary rock -----> metamorphic rock (heat and pressure) igneous ----> metamorphic rock (crystilisation) metamorphic-----> magma (melting) magma ----> igneous rock (cooling)
500
What is the mass color of magnetite?
Teal
500
What can be said about the relationship between the hardness of a mineral and its cleavage/fracture?
The lower the hardness, the more of a chance that it will crumble
500
What is the relationship between volcanoes and tectonic plates?
the collisions between the plates invovle enormous quantities of energy, these events often shake the earths crust, where volcanoes can form where the crust is weak (eureka page 323)

Why is it difficult to explore earth's interior?
Because geologists can only dig 12 km into the ground
