Plate Tectonics

QuestionAnswer
describes how the tectonic plates move on the Earth theory of plate tectonics
layer of the Earth that is made up of the crust and the upper mantle lithosphere
layer of the Earth that the tectonic plates move on asthenosphere
layer of the Earth that is solid and the most dense due to iron and nickel inner core
layer of the Earth that is liquid outer core
eruption of magma that occurs along plate boundaries and hot spots in Earth's crust volcanoes
movement of material due to the differences in temperature; in mantle, leads to movement of plates convection currents
sudden movement in Earth's crust due to plates rubbing as they try to slide past one another earthquake
type of boundary where the plates are moving away from each other; causes new sea floor and mid ocean ridges divergent boundary
type of boundary where the plates are moving toward each other to cause mountains, volcanoes, earthquakes, subduction zones convergent boundary
type of boundary where the plates are trying to slide past each other; leads to earthquakes transform boundary
occurs where denser oceanic crust is pulled under lighter continental crust subduction zone
formed when two continental plates collide and the crust is folded and pushed together mountains
when magma spreads out as plates move away from each other to from new ocean floor sea floor spreading
