| push-pull force | stress |
| the breaking, tilting, and folding of rocks | deformation |
| when rocks are squeezed together by a type of stress | compression |
| type of stress that pulls a rock apart | tension |
| causes rocks to twist or tear apart. The rocks simply bend or break apart | shearing |
| a break or crack along which rocks move | fault |
| the block of rock below the fault | footwall |
| the block of rock above the fault | hanging wall |
| mountains formed by blocks of rocks uplifted by normal faults | fault block mountains |
| formed when the block of land between two normal faults slide downward | rift valley |
| a bend in a rock | fold |
| an upward fold in a rock | anticline |
| a downward fold in a rock | syncline |
| able to break easily | brittle |
| rocks that bend easily | ductile |
| uplifted area created by rising magma | dome |
| the balancing between up and down forces | isostsay |
| underwater mountains that have a deep crack in them | rift valley |
| underwater mountains | mid ocean ridges |
| deep v-shaped valleys | trenches |
| the process of the ocean floor plunging back into the interior of the earth | subduction |
| plates that move apart | divergent boundaries |
| where one plate is being pushed under another | convergent boundaries |
| two plates grind past one another, usualy found at right angles | transform boundary |
| movement of fluid caused by unequal heating of the fluid | convection currents |
| islands that appear in a curved line | island archs |
| the shockwaves produced by an earthquake | seismic waves |
| an instrument that detects sesmic waves | seismograph |
| innermost layer of the earth | core |
| second layer of the earth, surrounds the inner core | outer core |
| layer of the earth that lies about the core | mantle |
| boundary between the earth's outermost layer and the mantle | moho |
| when a solid has the ability to flow | plasticity |
| the thin most outer layer of the earth | crust |
| crust beneath the oceans | oceanic crust |
| crust beneath the continents | continental crust |
| the topmost solid part of the earth | lithosphere |
| Asia, Europe, and Africa | largest landmass |
| North and South America | second largest landmass |
| Antartica | 3rd largest landmass |
| Australia | smallest landmass |
| a large area of very old rock exposed at its surface | shield |
| shape of the earths surface | topography |
| mountains, plains, plateaus | 3 main landscapes |
| height above sea level | elevation |
| the difference in a regions elevation | relief |
| natural landforms that reach high elevations | mountains |
| most mountains are apart of a group of mountains | mountian range |
| a group of mountain ranges in one area | mountain system |
| most mountain ranges and mountain systems are apart of a large system called | a mountain belt |
| flat land areas that are not far above sea level | plains |
| low, flat areas found inland on a continent | interior plains |
| low, flat areas along the coast | costal plains |
| broad, flat areas of land that rise more tan 600 meters above sea level | plateaus |
| a map used for navigation. Shows the correct shapes of continents but the sizes of land and water areas are distoreted | mercator projection |
| show all area correctly, but the shapes of the areas are distored on the projection | equal area projection |
