Unit 4b

3. mountains- mountains formed by the bending of rocks
5. crust- portion of earth's crust that lies beneath the oceans, it is thinner than continental crust.
6. maps- map that shows the shape and elevation of the land surface using contour lines, and shows other land features using symbols. Elevation- height above sea level. lines- on a map, a line that connects points of equal elevation above sea level Lithosphere- outermost layer of earth's surface, which is rocky and solid; includes the crust and the rigid part of the upper mantle. Continental crust-rocky material that makes up the continents, it is less dense and contains a greater amount of lighter colored minerals than oceanic crust.
7. boundary- form where lithospheric plates are moving away from each other
8. block mountains- mountains formed when rocks move along faults, leaving blocks of crv at different elevations.

1. the process in which one lithospheric plate slides under another; occurs a converging plate boundaries.
2. boundary- formed where two sections of earth's crust are colliding.
4. under a mountain range that forms where two parts of earth's crust are Mid-ocean pushing apart.
6. boundary a boundary between two lithospheric plates are sliding past each other.
