draw a picture of what a convergent plate boundary does
picture
what are the two types of crust
what is oceanic and continental
what plate movement causes mid-ocean ridges
what is divergent plate boundaries
what is lava
what is molten rock ejected by volcanoes in the form of a liquid
draw a picture of what a divergent plate boundary does
picture
which is more dense the continental crust or oceanic crust
what is the oceanic crust
what plate movement causes mid-ocean trenches
what is convergent plate boundaries/subduction
what is magma
what is an extremely hot liquid located under Earth's surface.
draw a picture of what a transform plate boundary does and give an example of one.
what is the San Andreas fault, the Queen Charlotte fault ext.
what is sea floor spreading
what is the process by which molten material adds new oceanic crust to the ocean floor and the ocean floor spreads apart
what plate movement causes mountains
what is convergent plate boundaries
what is subduction
what is the action or process in plate tectonics of the edge of one crustal plate descending below the edge of another.
what are the different types of divergent plate boundaries
what is oceanic and continental
what are the density of the oceanic crust and continental crust
what is the oceanic crust is 3.0g/cm and the continental crust is 2.7g/cm
what plate movement causes volcanos
give an example of and earthquake-prone area
California, ring of fire, ext
what are the different types of convergent plate boundaries
what is oceanic to oceanic, continental to continental, and oceanic to continental
what happens when new crust is created
what is it pushes the existing crust away from the ridge, leading to the expansion of the seafloor.
what plate movement causes rift valleys
what is divergent plate boundaries
what are convection currents
what is heat-driven cycles that occur in the air, ocean, and mantle. they also move the plates
