This is a boundary where 2 plates pull apart from each other
The 3 evidences that Hess used for his theory of sea floor spreading
The process that continually adds new material to the ocean floor
Scientists rejected Wegeners theory because he could not
The transfer of energy through empty space
These are deep underwater canyons that the ocean floor can plunge into
In a convection current, the cooler, deser fluid does this
The 3 evidences that Wegner used for his theory of continental drift
The process by which oceanic crust sinks beneath trenches
Who first proposed the theory of Continential drift?
Geologists study these waves to gather indirect evidence about the inner earth
A scientist who studies the forces that make and shape the earth
this theory that state that the pieces of the lithosphere are in constant but slow motion
Heat transfer by direct contact of matter particles is
Continental crust consists mainly of this rock
This is a boundary where 2 plates collide into each other
Heat transfer by movement of fluid is called
A break in the crust where rocks have slipped past each other
Name the factors that set convection currents in motion
Earth's lithosphere is broken into seperate sections called
This is the boundary where 2 plates slip pass each other
the oceanic crust is made of this type of rock
This is part of the mantle that can bend like plastic
This erupts through the valley of the mid-ocean ridge
The supercontinent that began to break apart 225 million years ago
