| Question | Answer |
| term scientists used to describe activities of continental drift and magma flow which create many of earth's physical features | plate tectonics |
| highest point | Mt. Everest |
| lowest point | Mariana Trench |
| a part of the earth's mantle tat flows creating mantle convection | asthenosphere |
| Scottish geologist who proposed the earth's convection currents were responsible for the movement of tectonic plates | Arthur Holmes |
| process by which oceanic plates are pushed under lighter continental plates | subduction |
| location of lithospheric plates moving away from each other | Divergent boundary |
| states that earth's outermost layer is fragmented into a dozen of so plates that are moving of a mobile material | plate tectonics |
| zone of frequent earthquakes and volcanic eruptions in the pacific ocean | Ring of Fire |
| super continent proposed by Wegener | Pangaea |
| number that indicates the size of an earthquake | magnitude |
| large ocean wave that is caused by sudden movement on the ocean floor | Tsunami |
| large rigid slab of solid rock that makes up the earth's lithosphere | plate |
| most common rock on earth; makes up the oceanic crust | basalt |
| core, mantle, crust | layers of the earth |
| steep walled valley on the sea floor adjacent to a continental margin | trench |
| German meteorologist who proposed the theory of continental drift | Alfred Wegener |
| a scientist who specializes in the study of earthquakes | seismologist |
| form the Greek meaning "to build" | tectonic |
| location of lithospheric plates moving toward each other | Convergent boundary |
| forerunner of the theory of plate tectonics, it proposed that a present day continents were once part a a singer super continent | continental drift |
| common rocks of the continental crust | andesite and granite |
| rigid, outermost layer of the earth, made up of crust and uppermost mantle | lithosphere |
| zone of earthquakes | seismic belt |
| the property of a solid that flows | plastic behavior |
| flow of the asthenosphere which plays a role in moving lithospheric plates | mantle convection |
| standard scale used to compare earthquakes | Richter scale |
| location of lithospheric plates sliding past each other | Transform boundary |
| a divergent plate boundary, located on the floor of the ocean | Mid-Atlantic Ridge |
| water is exchanged between the earth and the atmosphere | hydrologic cycle |
| water becomes vapor | evaporation |
| water vapor becomes liquid | condensation |
| rain, sleet, snow, hail | precipitation |
| lakes, ponds, rivers, oceans | surface water (80% of earth's water is surface water) |
| ground water | aquifers |
| oceans(97% of earth's water) seas, bays, and gulfs | salt water |
| salt water to fresh water | desalination |
| lake, streams, rivers, aquifers | fresh water |
| body of water completely surrounded by land, usually caused by glacial movement | lake |
| Which pieces of evidence did Wegener use to support his theory of continental drift? | fossils |
| seafloor spreading explains why... | the oldest part of the ocean floor is farthest from the mid-ocean ridge |
| energy released during and earthquake creates... | seismic waves |
