| Question | Answer |
|---|---|
| Pangaea | All the continents were once part of a supercontinent |
| Continental Drift | Which suggested that continents are in constant motion on the surface of Earth |
| Mid-Ocean Ridges | The mountain ranges in the middle of the oceans |
| Seafloor | The process by which new oceanic crust forms along a mid-ocean ridges and older oceanic crust moves away from the ridge |
| Normal Polarity | A state in which magnetized objects, such as compass needles, will orient themselves to point north |
| Magnetic Reversal | The magnetic field reverses direcition |
| Reversed Poarity | A state in which magnetized objects would reverse direction and orient themselves to point south |
| Plate Tectonics | Earth's surface is made of rigid slabs of rock, or plates, that move, with respect to each other |
| Lithosphere | The cold and rigid outermost rock layer |
| Divergent Plate Boundary | Forms where two plates separete |
| Transform Plate Boundary | Form where two plates slide past each other |
| Convergent Plate Boundary | Form where two plates |
| Subduction | The denser plate sinks below the more buotant plate in a process |
| Convection | The circulation of material caused by differences in temperature and density |
| Ridge Push | Rising mantle material at mid-ocean ridges creates the potential for plates to move away from the ridge with a force ridge push moves lithosphere in opposite directions away |
| Slab Pull | As a slab sinks, it pulls on the rest of the plate with a force |
| Isostasy | Is the equilibrium between continental crust and the denser mantle below it |
| Subsidence | The downward vertical motion of Earth's surface |
| Uploft | The upward vertical motion of Earth's surface |
| Compression | Squeezing stress |
| Tension | Stress that pulls something apart |
| Shear | Parallel forces acting in opposite directions |
| Strain | A change in the shape of rock caused by stress |
| Ocean Trench | Are deep, underwater troughs created by one plate subducting under another plate at a convergent plate boundary |
| Volcanic Arc | A curved line of volcanoes that forms parallel to a plate boundary |
| Transform Fault | Where tectonic plates slide horizontally past each other |
| Fault Zone | An area of many fractures pieces of crust along fault |
| Folded Mountain | Are made of layers of rocks that are folded |
| Fault-Block mountain | Are parallel ridges that firm where blocks of crust move up or down along faults |
| Uplifted Mountain | When large regions rise vertically with very little deformation |
| Plains | Is an extensive area of level or rolling land |
| Basin | Areas of subsidence and regions with low elevation |
| Plateau | Flat regions with high elevations |
