Ess 101 Exam One Study Guide
Questions With Answers.
plate tectonics - ANSWER- outer portion of the earth which consists of slabs of
lithosphere (upper most mantle and crust) that are in constant relative motion
three kinds of plate boundaries - ANSWER- divergent, convergent, transform fault
divergent boundary - ANSWER- moving away from each other
convergent boundary - ANSWER- moving towards each other
transform fault boundary - ANSWER- moving past each other
layers of earth from inner to outer / composition at each layer - ANSWER- 1. inner core:
solid nickel and iron
2. outer core: molten nickel and iron
3. lower mantle: solid dense rock
4. upper mantle: mostly solid rock
5. crust: solid less-dense rock
mineral - ANSWER- a naturally occurring, inorganic, crystalline solid with a definite
chemical composition; defined by 5 characteristics - crystalline(1), solid(2), definite
chemical composition(3), naturally occurring(4), inorganic(5)
rock - ANSWER- naturally formed, solid material composed of grains of one or more
minerals
crystalline - ANSWER- atoms are arranged in a regularly repeating, orderly structure,
called the crystal lattice
cleavage - ANSWER- tendency for mineral grains to break on distinct planes --
cleavage planes are the manifestation of uniform planes of relatively weaker bonds in
the crystal lattice of the mineral
ultramafic - ANSWER- >85% dark minerals
mafic - ANSWER- >45% dark minerals
intermediate - ANSWER- ~25-45% dark minerals
felsic - ANSWER- >25% dark minerals
