Seafloor Spreading

1. deepest flattest parts of the earth
8. a superheated water spout found at midocean ridges
10. a linear lowland area between two uplifted areas found at a divergent plate boundary
12. a divergent boundary between two oceanic plates
14. India into Asia
15. plate boundary "slip and slide"
16. steepest part of a continental margin
17. bump of sediment found at the base of a passive continental margin

2. continental volcanic arc due to oceanic-continental plate convergence
3. the Aleutian Islands and the islands of Japan are formed in this convergent boundary
4. stripes that form a symmetrical pattern around mid ocean ridges showing ancient pole reversals
5. the earths crust
6. area of high earthquake and volcanic activity around the Pacific ocean due to convergent plate boundaries
7. molten lava from the upper mantle that wells up forming new seafloor
9. an underwater volcano
11. forms at convergent boundaries
13. volcanic island shape that forms on the less dense of two oceanic plates at a subduction zone
