Things you should know:
Crust, Mantle vs. Lithosphere,
Asthenosphere - should know that mesosphere is lower mantle (below asthenosphere).
Plate Boundaries - Divergent
(has rift valley or mid-ocean ridge at boundary), Convergent (has trench
or folded mountains at boundary--not volcanoes--they are a short way away),
Transform (has fault at boundary).
We make new oceanic crust
(basaltic) at a divergent boundary
Know the meanings of the
words: isostasy, orogeny, subduction, transgression, aulocogen (failed
rift), orogen (mountain building event), ophiolite (a section of oceanic
lithosphere that gets wedged onto land when two continents collide).
The sequence of rock expected
when we have a transgression (from bottom to top) is: sandstone,
shale, limestone. We get the opposite for a regression
Red coloration usually indicates
a nonmarine environment, whereas gray usually indicates a marine environment
cratonic means on a stable
portion of a continent, orogenic means in an area near a plate boundary
(undergoing mountain building).
Know the difference between
cross bedding, planar bedding, and graded bedding
Know that a formation is
a unit of rock that is related somehow (but doesn't have to be exactly
the same rock) and is large enough to be visible on a map
Know the difference between
a stratigraphic column, a geologic map, a geologic cross section, and a
block diagram
Mature vs. immature sediments
- know the definitions of sorting and rounding
I expect you to remember
conglomerate, breccis, sandstone (and the 3 special types - graywacke,
arkose, quartz sanstone), shale.
