- 4. ocean with many active plate boundaries
- 8. abundant features on the Pacific Ocean floor due to lack of sedimentation
- 13. sediment derived from diatoms foraminifera and other organismal remains
- 14. a superheated water spout found at midocean ridges
- 16. finest particle size of sediment that takes the longest to settle
- 18. an underwater volcano
- 21. area of high earthquake and volcanic activity around the Pacific ocean due to convergent plate boundaries
- 22. continental margin with a narrow shelf and steep slope
Down
- 1. type of continental margin that does not mark a plate boundary
- 2. stripes that form a symmetrical pattern around mid ocean ridges
- 5. a linear lowland area between two uplifted areas found at a divergent plate boundary
- 6. forms at convergent boundaries
- 7. steepest part of a continental margin
- 9. deepest flattest parts of the earth
- 10. bump of sediment found at the base of a passive continental margin
- 11. the Aleutian Islands and the islands of Japan are formed in this convergent boundary
- 12. the earths crust
- 15. molten lava from the upper mantle that wells up forming new seafloor
- 17. sediment derived from weathering
