A Late Reminder for the Physical Geology Lecture Final
Sorry I didn't get to finish the new Power Point review, a few more things to review are:
The New Georgia Geology Notes. The main thing to remember are the 4 Provinces and the basic rock types in each one.
Valley & Ridge - Paleozoic Sedimentary Rocks.
Blue Ridge - Igneous and Metamorphic Rocks - highest topography in the state.
Piedmont - Igneous and Metamorphic Rocks - has more igneous rocks, e.g., the large granite bodies and the diabase dikes, which are the youngest igneous rocks in Georgia.
Coastal Plain - Late Mesozoic and Cenozoic Sediments
The Valley & Ridge, Blue Ridge, and Piedmont Provinces are all considered part of the Appalachian Mountains.
On the Mass Wasting Chapter - the cause is when Gravity overcomes Cohesion and Friction. Oversteepening of slopes is when natural support at the bottom of a slope is removed by erosion or excavation.
On the Surface Water Chapter - remember the definition of gradient, cut-bank erosion occurs on the outside of a meander bend, point bar deposition occurs on the inside of the meander. Oxbow lakes are cut-off meanders. Also remember Base Level - when it drops, down-cutting occurs; when it rises, deposition occurs.
On the Ground Water Chapter - remember the definitions of aquifer, the basics of well construction (reasons for grout and surface pad).
