4. Rocky material that makes up the continents; it is less dense and contains a greater amount of lighter colored minerals than oceanic crust.
6. Form where lithospheric plates are moving away from each other.
7. Mountains formed by the bending of rocks.
8. Mountains formed when rocks move along faults, leaving blocks of crust at different elevations.
10. Under sea mountain range that forms where two parts of earth’s crust are pushing apart.
11. On a map, a line that connects points of equal elevation above sea level.
12. Portion of earth’s crust that lies beneath the oceans; it is thinner than continental crust.
13. The process in which one lithospheric plate slides under another; occurs at converging plate boundaries.

1. Outermost layer of earth’s surface, which is rocky and solid; includes the crust and the rigid part of the upper mantle.
2. Height above sea level.
3. Formed where two sections of earth’s crust are colliding.
5. A boundary between two lithospheric plates are sliding past each other.
9. Map that shows the shape and elevation of the land surface using contour lines, and shows other land features using symbols.
