Across
- 3. outermost layer of earth’s surface, which is rocky and solid; includes the crust and the rigid part of the upper mantle.
- 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. formed where two sections of earth’s crust are colliding.
- 8. height above sea level.
- 10. the process in which one lithospheric plate slides under another; occurs at converging plate boundaries.
- 11. form where lithospheric plates are moving away from each other.
- 13. under sea mountain range that forms where two parts of earth’s crust are pushing apart.
Down
- 1. on a map, a line that connects points of equal elevation above sea level.
- 2. mountains formed when rocks move along faults, leaving blocks of crust at different elevations.
- 5. a boundary between two lithospheric plates are sliding past each other.
- 7. map that shows the shape and elevation of the land surface using contour lines, and shows other land features using symbols.
- 9. mountains formed by the bending of rocks.
- 12. portion of earth’s crust that lies beneath the oceans; it is thinner than continental crust.
