NAME _______________________________________
Chapter 5, Section 5: The Theory of Plate Tectonics
1. ________________ - a section of the lithosphere that slowly moves over the asthenosphere
carrying pieces of continental and oceanic crust
2. Plates carry the ___________________________ or parts of the _________________
___________ or _________________.
3. ___________________________________ combined what geologists knew about seafloor spreading, Earth’s plates, and continental drift into a single theory.
4. The theory of plate tectonics states that _____________________________________
_____________________________________________________________________
_____________________________________________________________________.
5. The edges of Earth’s plates meet at plate ________________________ that extend deep
into the ____________________________.
6. ________________ - a break or crack in Earth’s lithosphere along which the rocks move
7. When two plates collide, the ___________________ of the plates determines which one
comes out on top.
8. When a plate carrying oceanic crust collides with a plate carrying continental crust,
_____________________________ occurs. The oceanic plate is more dense so it
_____________________________________________________________________.
9. When two plates carrying continental crust collide subduction does not take place because
______________________________________________________________. Instead,
___________________________ are formed.
10. Along a _________________________ boundary, crust is neither created nor destroyed.
