Plate Tectonics Vocabulary
Term | Definition |
---|---|
subduction zone | area that oceanic plates sink down into the asthenosphere |
reverse fault | fault in which the hanging wall moves up relative to the footwall |
outer core | layer that is liquid |
transform boundary | type of boundary that is between two tectonic plates that slide past each other |
sea floor spreading | process in which new oceanic lithosphere is created as older materials are pulled away |
mantle | layer between crust and core |
mesophere | strong, lower part of the mantel, between asthenosphere and outer core |
tension | stress that happens when plates pull apart from each other |
normal fault | tectonic forest that push on rocks cause this kind of fault |
crust | the outermost layer of the Earth |
stress | the amount of force that is put on a material |
inner core | solid, dense center of the Earth |
tectonic plates | the lithosphere is divided into pieces form these |
continental drift | the theory that continents can move apart from one another and have done so in the past |
core | center of the Earth |
fault | surface along which rocks break and slide past each other |
asthenosphere | soft layer of mantle on which pieces of the lithosphere move |
compression | stress that happens when two plates collide |
lithosphere | layer that is above the asthenosphere |
divergent boundary | type of boundary between plates that move away from each other |
strike slip fault | type of fault in which the two fault blocks move past each other horizontally |
convergent boundary | type of boundary between plates tat collide |
folding | occurs when rock layers bend due to stress |
plate tectonics | the theory that Earth's lithosphere is divided into tectonic plates that move around on top of the asthenosphere |
