2) Similar fossil assemblages on the east 3) Coal and plant fossils in
coast of the Americas and the west coast of Antarctica 4)
3. Composed of crust plus some of the Lithosphere
mantle
4. Mid-Ocean Ridge An undersea mountain chain where new
ocean floor is produced;
a divergent plate boundary.
5. Asthenosphere The soft layer of the mantle on which the
lithosphere floats.
*Composed ONLY of mantle material*
6. The Wilson Cycle A predictive model that relates the life cycle
of an ocean basin to plate tectonics
7. Embryonic (ocean basin) Uplift; East African rift valleys

malayas
13. Cross-section of a Mid-Ocean
Ridge (with labels)
14. Why are satellites used to 1) They can cover areas where ships
map the ocean floor? have not pro- duces surveys
2) They can "see" large areas of the
seafloor at one time
3) The shape of the ocean surface itself
reflects large features on the seafloor below
15. Seamounts Volcanic features on the ocean floor that are
greater than 1,000 meters tall
16. Black Smokers Hydrothermal vents that emit the water at high
tem- peratures and dark metal sulfides
