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