OCN 201 Exam 1
from evaporation of sea water + in young ocean basins, which is long + narrow - answer
thick deposits of salt form in the ocean
normal faulting implying tension + extension - answer mid-ocean ridge axial valley is
formed by
equal standing density will determine how high it will float, how deep it will sink - answer
isostasy
those that tend to form solids, even at high temp. - answer refractory elements
rapid accretion of cold, icy, water rich planetesimals - answer why does earth have
ocean?
Fe, O, Si, Mg - answer earth is mainly made of
ride on the backs of the moving lithospheric plates - answer continents drift across
the surface of the earth b/c they
high heat flow, shallow seismicity, sediment absent
tensional stress: brifting - answer mid ocean ridge
slab pull (considered the most valuable mechanism) - answer driving force of plate
tectonics
convection in earths mantle - answer the motion of lithosphere plates across earths
is caused by
atmosphere, crust, mantle, outer core, inner core - answer from outside to inside the
earth consists of
paleomagnetism rocks - answer magnetic minerals in rocks align with earths
magnetic field when rocks solidify
those that tend to form gases in low temp - answer volatile elements and compounds
underwater seamounts with flat tops - answer guyots
the depth where the rate of delivery of calcium carbonate is= to the rate it dissolves
