Plate Tectonics
20
plate : A piece of the earth that causes the earth's continents to drift.
plate tectonics : Earth's plates, and there movement in a theory is called_______ _______.
divergent : When earth's plates move away from each other is called a_______ boundary.
convergent : When earth's plates come together it is called a_______ boundary.
transform : When earth's plate slip pass each other it is called a_______ boundary.
faults : _______ break into earth's crust when rock slip pass each other.
Pangaea : When all of earth's plates were together into one big continent.
continental drift : The idea where Pangaea split apart and then drifted apart.
sea floor spreading : The process of when the plates move and and more material is add to the sea floor.
deep ocean trenches : When one plate sinks under anther and forms a canyon.
subduction : This occurs when a plate sinks below the deep ocean trenches and goes back into the mantle.
rift valley : Where plates diverge on land and forms a valley.
mid ocean ridge : Some mountains that are rising in the middle of some ocean floors.
wegener : According to _______'s hypothesis the plates were all together until they drifted apart.
formed : As the plates get _______ at one end the other side is sending the older plate back to the mantle.
convection : Plates are moved by _______ waves.
volcanoes : These are form at convergent boundaries and are most like to erupt.
mountains : _______ form when two plates of the same density rise.
density : ______ decides if the plates sink or if the form mountains/volcanoes.
molten material : ______ rises up through the seam of plates.
