SHAPING EARTH’S SURFACE

2. 4.2 INFORMATION

3. C. OCEAN BASINS

4. MID-ATLANTIC RIDGE

5. LAVA FORMS NEW CRUST
At convergent plate boundaries and divergent plate boundaries, lava hardens and forms new crust

6. LAVA FORMS NEW CRUST
At an oceanic divergent plate boundary, newly formed crust is added to the edges of the plates as new ocean crust

7. MID-OCEAN RIDGES
Long, narrow mountains formed by magma at divergent boundaries

8. MID-OCEAN RIDGES
Three-quarters of all lava erupts at mid-ocean ridges

9. MOUNTAINS FORM
Most mountains form near plate boundaries because folding and crumpling usually occur at the edges of plates

10. MOUNTAIN RANGES
Large mountain ranges form when two continents collide at a convergent plate boundary.

11. HIMALAYAS
The Himalayas are the world’s largest and highest mountain range, and they are still growing
