Plate tectonics Flashcards
What causes the tectonic plates to move
carried along currents in the mantle
what are the 3 main types of plate boundaries
tectonic, ocean ,and crust
what are plate tectonics made of
continental and oceanic crust
what happens at a divergent boundary
two plates move apart from each other
what happens at a convergent boundary
one plate often subducts beneath each other
plate tectonics results in
mountain building
what is plate tectonics
Earth’s outer shell the lithosphere
what is the lithosphere
The lithosphere consists of seven or eight major plates
Tectonic plates consist of
Tectonic plates are large pieces of the Earth’s lithosphere that move and interact with each other.
Seafloor spreading occur
along mid-ocean ridges-large mountain ranges rising from the ocean floor.
