|---|
| sedimentary rocks | form from compaction and cementation of sediments |
| rock cycle | processes that form and change rock from one kind to another |
| minerals | natural, solid materials; building blocks of rock |
| ores | minerals mined for useful metals or nonmetals |
| fossil fuels | formed from the remains of living things |
| plate tectonics | lithospheric plates move |
| convection current | heating, rising, cooling, sinking of amtter |
| divergent plate boundary | plates are moving apart |
| convergent plate boundary | plates are colliding |
| transform plate boundary | plates are sliding past each other |
| subduction zone | one lithospheric plate slides under another |
| Pangaea | supercontinent; one large land mass |
| volcano | mountain built of cooled lava, volcanic ash, cinders, rock |
| volcanic eruption | constructive and destructive |
| magma | liquid rock from mantle |
| lava | liquid rock that flows out onto Earth's surface |
| vent | opening in a volcano where magma flows out |
| tension | force that pulls rocks apart |
| shearing | forces that push on rocks from either side of fault |
| compression | force pushing on rock from opposite directions |
| normal fault | break in rock caused by tension forces (hanging wall falls) |
| reverse fault | hanging wall is pushed up by compression |
| thrust fault | break in rock caused by shearing forces |
| fault block mountain | normal fault uplifts a section of rock |
| topographic map | uses contour lines and intervals to show elevation |
