Study guide for first exam

Format:  20 multiple choice, 1 short answer/essay, 3 images/diagrams

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.
