Document Summary
P: overfishing, ocean acidification (fossil fuel, hydrocarbons, releases. Atlantic ocean = 2nd largest/expanding at the expense of the pacific ocean as a result of plate tectonics. Southern ocean" marginal region that goes around the coast of antarctica. Clicker question: how deep is the ocean (on average?: 40m, 400m, 4000m, 40000m, 400000m. /distribution between land/oceanography majority of land sits near sea level change sea level by small amounts > it reduces surface area by a lot (shrinks amount of land) ex. exponential decay oceanic crust vs. continental crust. Older 4 billion years (earth assumed to be c. 5 billion) Basalt (created from volcanic material, as a result of earth"s interior) Density = 3 gm/cm^3 aka: thinner, and deeper aka: biggest difference between o. crust and c. crust. Aka: the material at the absolute bottom of the ocean, can be found at the highest point on earth as a result of:
