float
rise
Seafloor spreading occurs when two plates
are colliding into each other
when one plate subducts beneath another
slip past each other creating earthquakes
moving away from each other creating ridges
Rocks found along divergent boundaries are youngest away from the plate boundary.
True: rocks are younger as you move away from the boundary
False: rocks are younger closer to the boundary
When plates move away from each other it creates a ___________ boundary.
convergent
transform
shearing
divergent
When plates move toward each other they create a _________________ boundary.
compression
convergent
divergent
transform
When plates slide past each other, they create a __________ boundary.
convergent
tension
divergent
transform
Which process builds or makes crust?
sea floor spreading
subduction
earthquakes
shearing
Which process destroys crust?
sea floor spreading
convection currents
subduction
law of conservation of mass
Why wasn't Wegner's Continental Drift theory accepted by other scientists?
People felt there wasn't enough evidence.
He could not explain how the plates moved.
The evidence didn't make sense.
People were closed minded.
As we go down
temperature increases
density increases
pressure increases
and we know that the crust is separate pieces
