| Question | Answer |
|---|---|
| What is Pangea? | The super continent, that broke up ~150,000,000 BP, it began about 300,000,000 BP. |
| What is Convection? | The transfer of heat through a heated fluid |
| What is Conduction? | The transfer of energy through direct contact. |
| What is Radiation? | The transfer of energy through space |
| What is the process by which the earth formed through gravity bringing together the smaller particles of matter to from a planet? | Accretion |
| What is the outer layer of the earth that is made out of rock; makes the continent and oceans bottom? | The crust |
| What is the outer layer of the core, made of molten metals; iron and nickel? (It gives the earth its magnetic fields.) | The outer core |
| What is the center of the earth made of iron and nickel that is solid? | The inner core |
| What is the lithosphere? | The layer of the earth that is made of the upper layer of the mantle and the earth's crust. |
| What is the asthenosphere? | The part of the mantle below the lithosphere, that has the consistency of asphalt it contains the convection currents that cause the movement of the earth's plates. |
| What is sea floor spreading? | The process that continually adds material to the sea floor by molten rock hardening and then being pushed by new molten rock. (makes the Atlantic wider.) |
| What is the San Andrea fault? | A transform boundary in California |
| What is subduction? | The process where a heavier oceanic plate slides under a lighter continental plate. (Pacific plate goes under Eurasian plate.) |
| What is a transform boundary fault? | The place where two plates slide or slip past each other in opposite directions. |
| What are three examples of a Rift? | The Great African Rift, The Rhine Valley, and the Mid-Atlantic Ridge. |
| What are the eight major plates? | Eurasian, Atlantic, Australian-Indian, South American, North American, Antarctic, Nazca, and African. |
| What are the four major layers of the earth? | The outer core, the inner core, mantle and crust |
| Sea floor spreading makes what? | New ocean bottom |
| The Mid-Atlantic is an example of what? | Divergent boundary |
| What causes the magnetic fields of the earth? | Convection currents of the outer core. |
| What are common rocks of the crust? | Granite and basalt; hardened magma |
| What are examples of subduction? | The pacific plate sub ducting under the Eurasian plate |
