| Geology | the study of people and locations and how they relate |
| crust | the outermost part of the earth; liquid |
| core | the inner most part of the earth; solid partly liquid |
| mantle | the middle part of the earth; with magma bubbles |
| continents | seven large landforms on the earth |
| continental drift theory | pangea drifted apart; fossils found on far apart continents |
| sea floor spreading | that as time passes the earth makes more crust |
| convection | hot air rises, moves plates away from hot zone, then cools and falls |
| spreading | when plates pull apart from each other; earthquakes and volcanoes form |
| subduction | when oceanic and continental plate crash; O is heavier so pushes up C plate |
| converging | 2 plates of same type collide; if both are C the push up form mtns. if both are O then one pushes up islands form |
| faulting | when plates slide or grind past each other |
| island | a piece of land completely surrounded by water |
| plate tectonics | earths outer shell is not one solid piece of rock |
| pangea | supercontinent; all continents were once joined as one large landmass |
| archipelago | a string of islands |
| penninsula | a piece of land surrounded on three sides by water |
