Everything else
Heat transfer through the movement of heated fluid
Convection
In seafloor spreading, along what landform does molten material rise up?
mid ocean ridge
Pieces of the lithosphere
plates
Wegner's hypothesis that all of the continents were once joined together.
continental drift
Continental convergent boundaries create this
mountains
Heat transfer by direct contact of molecules of matter
conduction
The youngest oceanic crust can be found here
near the mid ocean ridge
The movement of the Earth's plates are because of this
convection currents
Name of the super continent that Wegner came up with.
Pangea
These boundaries slip past each other in opposite directions
transform boundaries
Equation of density
mass divided by volume, M/V
If new ocean floor can create new crust quicker than it can be subducted, will the ocean grow or shrink?
the ocean will grow
The theory that the Earth's plates are in constant motion is called
plate tectonics
Why didn't people believe Wegner?
because they couldn't prove how the continents moved.
Transform boundaries creates these
Earthquakes
Convection currents occur in this layer of the earth.....not mantle.
asthenosphere
Mid ocean ridge happens at this kind of boundary
divergent boundary
A rift valley occurs between this type of boundary
divergent boundary
The 3 pieces of evidence that Wegner used for his hypothesis.
fossils, landforms, and climate.
This is the PROCESS when the ocean floor sinks back into the mantle
subduction
Convection currents form in the mantle when heated materials become...
less dense
The mid ocean ridge means that this ocean is getting larger.
Atlantic ocean
The thickest part of a plate lies below this
a mountain
This boundary forms when two plates come together
convergent boundaries
