6. rocky material that makes up the continent; it is less dense and contains a greater amount of lighter color mineral than oceanic crust
8. the process in which one lithospheric plate slides under another; occurs at converging plate boundaries
11. formed where two sections of earths crusts are colliding
12. outer most layer of earths surface, which is rocky and solid; includes the crust and the upper part of the mantle

1. height above sea level
2. mountains formed when rocks move along faults, leaving blocks of crust at different elevations
4. portion of earths crust that lies beneath the ocean; it is thinner than continental crust
5. formed where lithospheric plates are moving away from each other
6. on a map, a line that connects points of equal elevation above sea level
7. maps that shows the shape and elevation of the lands surface using contour lines, and shows other land features using symbols
9. mountains formed by the bending of rocks
10. a boundary between two lithospheric plates are sliding past each other
