Plate Tectonics

3. a type of boundary that involves plates sliding against each other
7. the crust is divided into the continental and _______ crust
10. this is an example of what happens at divergent boundaries
12. scientist found theses on both Australia and southern Asia as evidence that the continents were once connected
13. forms as continental plates push against one another
15. a type of boundary where tectonic plates move into one another
16. this force causes denser material to fall
17. are caused when plates slide past one another;

1. a large mountain range that lies underwater in between continents.
2. this layer contains parts that are moving at a slow rate
4. advancements in this area has allowed scientist to better understand plate movement
5. this layer of the Earth heats the mantle and causes denser magma to rise
6. this is a factor along with temperature that causes convection currents in the mantle
8. a type of boundary where plates are pushed away from one another
9. known as a super-continent where all the continents where one large landmass
11. this happens when hot material in the mantle rises reaches the surface cools and sinks back into the mantle; repeated cycle
14. made up of the crust and upper mantle; make up of plates that are broken into sections
