tectonics plates

2. An area of many fractured pieces of crust along a large fault
6. parallel ridges that form where blocks of crust move up or down along faults
7. Are deep underwater troughs created by one plates subducting under another plate at convergent plate boundary
9. A state in which magnetized objects would reverse direction and orient themselves to point geographically south
10. When large regions rise vertically with very little deformation form
12. new oceanic crust forms along a mid-ocean ridge and older oceanic crust moves away from the ridge
14. The magnetic field_____directions

1. all continents that were once connected as a supercontinent
3. Mountain ranges in the middle of the ocean
4. A curved line of volcanoes that forms parallel to a plate boundary
5. magnetized objects, such as compass needles, will orient themselves to point geographically north
8. Are made of layers of rock that are folded
11. fault Where tectonic plates slide horizontally past each other
13. that continents are in constant motion on the surface of the earth
