Plate Tectonics
| Question | Answer |
|---|---|
| crust | the thin and solid outermost layer of the earth |
| mantle | the layer of rock beetween the crust and core |
| core | the center of the earth |
| lithosphere | the solid outer layer of the earth that consists of the crust and the rigid upper part of the mantle |
| asthenosphere | the soft layer of the mantle on which tectonic plates move |
| mesosphere | the strong, lower part of the mantle between the asthenosphere and the outer core |
| tectonic plate | a block of lithosphere that consists of the crust and the rigid outermost part of the mantle |
| continental drift | the hypotesis that states that the continents once formed a single landmass, broke up, then drifted to thier present spot |
| sea-floor spreading | when new ocean floor forms when magma rises |
| plate tectonics | the theory that explains how large pieces of the earths crust move |
| convergent boundary | the boundary formed by the collision of 2 plates |
| divergent boundary | the boundary between 2 plates that are moving away from each other |
| transform boundary | the boundary between plates that are sliding past each other |
| compression | stress that occers when forces act to squeeze an object |
| tension | stress that occurs when forces act to stretch an object |
| folding | the bending of rock layers due to stress |
| fault | a break in a body of rock |
| subsidence | the sinking of regions of the earths crust |
| uplift | the rising of regions of the earths crust |
