Plate Tectonics
study guide
| Question | Answer |
|---|---|
| what type of boundary occurs at the continental-continental collision | convergent |
| what geologic feature forms at a continental-continental collision | mountian |
| going to the surface to the center of the earth, list the layers in order | lithosphere, asthenosphere, mesosphere, outer core, inner core |
| tectonic plates are large pieces of lithosphere that float on top of the | asthenoshere |
| who was Alfred wegener | German scientist who dicovered the continental drift |
| tell me 2 ways the theory of continental drift was supported | age of rocks, magnetic reversal, found the same fossils |
| t or f oceanic crust is younger at a ridge and older near the trench | true |
| where do convection currents take place | asthenosphere |
| what do scientist think move the tectonic plates | convection currents |
| what two types of plate collision form mountain ranges | continental and oceanic |
| why do you think fossils are sometimes found on the top of mountians | there was on ocean there |
| how does the mid ocean ridge form | the divergent boundaries move apart and the lava shoots out |
| what are Pangaea and panthalassa | land and ocean |
| what do tectonic plates do at a divergent boundary | earthquakes |
| what type of volcano is the worse | strato |
