minerals
Silicate where four O atoms of each tetrahedron bond to an adjacent tetrahedra.
What is a framework silicate?
Molten rock beneath the earth's surface
what is magma?
The san andres fault and a strike-slip fault are what kind of boundary's?
transfrom plate boundrey
What are three main types of plate boundaries? What are common examples
convergent, divergent, transform
T or F
Amber is a mineral?
False, inorganic
Differentiate between earths compositional layers, and the mechanical layers.
Compositional: crust, mantle, and core
Mechanical: Lithosphere, Asthenosphere, Mesosphere, Outer Core, Inner core
rift valleys, such as the great rift valley in africa, are created by
divergent plate bounderies
Why does oceanic plate subduct?
Oceanic crust is denser – mafic rock (iron and
magnesium)
Name four of five classifications of a mineral.
-naturally occurring
-solid crystalline substance
-generally inorganic
-specific chemical composition
-specific atomic arrangement in 3D space.
Generates earths magnetic field
What is the outer core?
Sciensists who originally proposed the concept of continental drift?
Who is alfred wegener?
Quartz is what kind of silicate?
Framework
two minerals that have the same chemical composition but a different crystal lattice structure.
What is a polymorph?
A balance/equilibrium of "blocks" of the lithosphere “floating” on the
asthenosphere.
Mantle isostacy
Scientist who introduced modern plate tectonic theory, he also was the first to explain the formation of volcanic islands and hotspots.
Who is John T. Wilson?
Albite is associated with what cation?
Sodium(Na)!
What characterizes the non-silicate sulfate group?
sulfate ion (SO42-)
ex) Gypsum CaSO4·2(H2O), Anhydrite CaSO4
What is earths mantle made out of?
silicate rocks rich in magnesium and iron (ultramafic rock – peridotite)
What drives plate motions?
pull up pick
What's in example of a polymorph?
diamond & graphite, aragonite & calcite
