| used to measure the movement of tectonic plates | global positioning system |
| hardens to form new rock at mid-ocean ridges | magma |
| stress that squeezes a rock layer | compression |
| stress that stretches a rock layer | tension |
| stress that causes rock layers to slide past one another | shear |
| big pieces of Earth's lithosphere | tectonic plates |
| the raising of a rock layer | uplift |
| the sinking of a rock layer | subsidence |
| the large super-continent | Pangaea |
| when Earth's magnetic poles change | magnetic reversal |
| underwater mountain chains running through the oceans | mid-ocean ridges |
| boundary where two plates collide | convergent boundary |
| boundary where two plates move away from each other | divergent boundary |
| fault that forms as a result of tension | normal fault |
| fault that forms as a result of compression | reverse fault |
| fault that forms as a result of shear | strike-slip fault |
| the area where two tectonic plates meet | boundary |
| bending of rock | folding |
| deep cracks that form between two plates that pull away from each other | rift zone |
| scientist who proposed the idea of a super-continent and continental drift | Alfred Wegener |
| the process by which the shape of a rock changes because of stress | deformation |
| the crust and upper mantle of the Earth | lithosphere |
| when one plate moves under another | subduction |
| folded mountains form with this type of stress | compression |
| the three types of folds | anticline, syncline, monocline |
