Asthenosphere
Mesosphere
Lithosphere
Crust
Which of the following is true regarding the composition of the lithosphere?
The lithosphere is mostly liquid, with some medium-density materials, such as silicon.
The lithosphere is more plastic and flows slowly compared to the solid crust of Earth.
The lithosphere includes the core and the lower portion of the mantle.
The lithosphere includes the crust and the uppermost portion of the mantle, which is sold and rigid.
As you travel from the crust to the core, how would temperature, pressure and density of the material change?
They would all increase
They would all decrease.
Nothing, the layers are made of the same material throughout
Temperature would decrease, but pressure and density would increase
The continental crust is
thinner than the oceanic crust
thicker than the oceanic crust
the same thickness as the oceanic crust
The layer is divided into two: the continental and oceanic.
Crust
Mantle
Core

how rigid each layer is
the thickness of each layer
the temperature of each layer
What distinguishes chemical layers of Earth?

According to plate tectonic theory, new crust is created at _________ boundaries
convergent
divergent
transform
normal
Divergent plate boundaries can be defined as areas where plates
move in opposite directions
move in opposite directions past each other
move in opposite towards each other
move in opposite away from each other
Which letter is closest to the divergent boundary in the cross section here?
a
b
c
d
Why is the ocean shallower where there are divergent plate boundaries?
there is less water in that part of the ocean
new sea floor “floats” because is hot and has a low density.
the sea floor there is not as heavy as the surrounding sea floor.
the oceanic crust there is thicker.

mountains
volcanic islands
What geological feature would an continental-continental convergent boundary create?
volcanic mountains
mountains
volcanic islands

What would you be most likely to find at a convergent boundary between an oceanic and oceanic plate?
Mountains
Volcanoes
Mid-Ocean Ridge
Rift
A subduction zone is formed...
when the oceanic crust sinks below the continental crust
at every type of convergent plate boundary
at every type of divergent plate boundary
at transform boundaries
The Aleutian Islands and Aleutian Trench are an example of what type of plate boundary?

What is the name of the theory that tectonic plates are moving because of the movement of magma in the mantle. The movement is caused by the magma heating and cooling and drags the plates along with it.
Slab pull
Ridge push
Convection currents
Scientists think that convection currents that move the plates flow in Earth's
Continental crust
Oceanic crust
mantle
outer core
When the force of gravity pulls a lithospheric plate downward and away from a ridge pushing it toward a trench.
Sea Floor Spreading
Subduction
Ridge Push
Slab Pull
When the force of subduction and gravity moves a lithospheric plate downward into a trench and pulls it away from a ridge.
Sea Floor Spreading
Subduction
Ridge Push
Slab Pull
Which Theory of plate movement occurs as oceanic crust moves away from the mid-ocean ridge and becomes cooler and more dense, sinking into a trench?
convection
ridge push
slab pull
What is slab pull?
cooler, denser crust sinks (is pulled) into the mantle along a trench
when edges become denser and gravity pulls them downward and away from one another
currents just beneath Earth's crust flow very slowly, causing movement in the plates above them
folding and crumpling and sliding upward creating mountains
Identify the three possible driving forces of plate tectonics
conduction
convection
Ridge push
slab pull
