Theory that the lithosphere is divided into tectonic plates that move around on top of the asthenosphere; the motions of tectonic plates.
the theory that continents can drift apart from one another and have done so in the past.
huge pieces of the lithosphere that move around on top of the asthenosphere; consist of the crust and the rigid, uppermost part of the mantle.
The process by which new oceanic lithosphere forms at the mid-ocean ridge
the boundary between two colliding tectonic plates
the boundary between two tectonics plates that are moving away from each other
boundary between two tectonic plates that are sliding past each other
all earth; super-continent that existed almost 245 million years ago
is a type of strain that occurs when rock break because of stress
is a type of strain that occurs when rock bend because of stress
when stress builds up and is released to cause seismic waves to vibrate and shake
the amount of force per unit area that is put on a rock
any change in a rocks shape volume caused by stress; deformation
Mid- Ocean ridge
is the combination of all the Earth's mid-ocean ridges
the rising of regions of Earth's crust to higher elevations
the sinking of regions of Earth's crust to lower elevations
the region where oceanic lithosphere sinks down into the asthenosphere at a convergent boundary
the direction of a magnetic field
crust that is thin and made of relatively dense materials
crust that is thick and made of relatively light weight materials
