Academic Earth Science NB# Name __________________ Vocabulary List #3- Plate Tectonics 1. The giant supercontinent that once existed Pangaea 2. It states that the Earth’s crust is broken up into plates Theory of Plate Tectonics 3. The type of boundary where two plates move apart Divergent 4. An opening in the crust where new crust is made Rift valley 5. The type of boundary where two plates come together Convergent 6. When one plate goes under another into the mantle (at a trench) subduction 7. The type of boundary that is formed when two plates slide past each other transform 8. States that new ocean crust is made at mid-ocean ridges and old crust is destroyed at subduction zones 9. A hot place in the mantle where magma rises to the surface in the middle of a plate 10. Motion resulting from material moving from warmer to cooler areas.
