the center.
a. asthenosphere, lower mantle, lithosphere, outer core, inner core
b. lithosphere, asthenosphere, lower mantle, outer core, inner core
c. asthenosphere, lithosphere, lower mantle, outer core, inner core
d. lower mantle, asthenosphere, lithosphere, outer core, inner core
e. lithosphere, lower mantle, asthenosphere, outer core, inner core - ✔✔B
✔✔Which layer is the least dense
a. upper mantle
b. asthenosphere
c. crust
d. outer core
e. lower mantle
f. inner core - ✔✔C
✔✔What caused the layers of the Earth to form?
a. Physical regulation
b. Substitution
c. Deportation
d. Chemical differentiation - ✔✔D
✔✔MOR stands for - ✔✔Mid-Ocean Ridge
✔✔The seafloor sinks as it moves further away from the rift zone, because it becomes
___ as it cools.
a. more dense
b. less dense
c. darker in color
d. lighter in color - ✔✔A
, ✔✔Sediment cover _______ fitter away from the MOR.
a. decreases
b. increases - ✔✔B
✔✔___ is the force applied to plates at spreading centers.
a. inertia
b. ridge push
c. convection
d. slab pull - ✔✔Ridge Push
✔✔What happens to both subducted and accreted sediments when they are subjected
to the pressures at a convergent margin?
a. weathering, erosion, and deposition
b. melting
c. metamorphism - ✔✔a?
✔✔Who was the one man responsible for the development of the theory of plate
tectonics?
A J. Tuzo Wilson
B Harry Hess
C None of the choices are correct.
D an unknown German scientist
E Alfred Wegener - ✔✔B
✔✔Why does the mid-ocean ridge sit higher than the surrounding seafloor? - ✔✔We
know that at a spreading center the lithosphere arcs up, developing a wide bulge on
Earth's surface at a mid-ocean ridge. Whether it's pushed up from below, or swollen
from the heat escaping the Earth's interior, we don't know for sure.
✔✔The conclusions from a study are only as good as the __________ is/are.
A presentation
B tests
C All of the choices are correct.
D location
E financial backers - ✔✔B
✔✔An educated guess that has passed repeated testing becomes a hypothesis. -
✔✔False
✔✔The laws of thermodynamics are considered ________.
A hypotheses
B theories
C facts
