Earth Sci Ch 8
| Question | Answer |
|---|---|
| the equilibrium between continental crust and the denser mantle below it | isostasy |
| the downward vertical motion or earth’s surface | subsidence |
| the upward vertical motion of earth’s surface | uplift |
| squeezing stress | compression |
| stress that pulls something apart | tension |
| parallel forces acting in opposite directions | shear |
| change in the shape of rock caused by stress | strain |
| deep, underwater troughs created by one plate subducting under another plate at a convergent plate boundary | ocean trenches |
| curved line of volcanoes that forms parallel to a plate boundary | volcanic arc |
| tectonic plates slide horizontally past each other | transform faults |
| made of layers of rocks that are folded | folded mountains |
| parallel ridges that form where blocks of crust move up or down along faults | fault-block mountains |
| large regions rise vertically with very little deformation | uplifted mountains |
| extensive area of level or rolling land | plain |
| areas of subsidence and region with low elevation | basins |
| flat regions with high elevations | plateaus |
| plates are moving apart | divergent plate boundary |
| forms when plates slide by each other | transform plate boundary |
| plates come together | convergent plate boundary |
| area of many fractured pieces of crust along a large | fault fault zone |
