name the six physiographic regions of Georgia
Valley and Ridge, Blue Ridge, Piedmont, Sand Hills, Southern Coastal Plain, and
Flatwoods
what is the oldest, most mature landscape of the Southeast?
Piedmont
hydrology equation
P = ET + Q + change in S
breakdown of hydrology equation
Precipitation, Evaporation and Transpiration, water discharge, Storage of water in soil
soil
the layer(s) of generally loose mineral and/or organic material that are affected by
physical, chemical, and/or or biological processes at or near the planetary surface, and
usually hold liquids, gases and biota and support plant.
soil functions
Plant growth media, regulate water supply, recycle raw materials, habitat for soil
organisms, engineering medium
the four processes
additions, losses, transformations, translocations
additions
largely humus additions to the A horizon
losses
losses from the soil profile
including soluble minerals during weathering and surface erosion
transformations
via chemical or physical modification such as primary minerals to secondary minerals
due to weathering reactions or humus synthesis
translocations
examples include clay and iron from the A and E horizons into the B. Transport of B and
C horizon material to the surface by termites, ants, or burrowing rodents.
how many feet in an acre?
43,560 sq feet
how many hectare in an acre?

pedogenesis
describes the formation and development of the soil profile
pedon
the three-dimensional body of soil used as the soil base of reference
shape of silicate
tetrahedron
, weathering of feldspar
accounts for much of the potassium and calcium found in the soil
micas
tetrahedra are arranged in sheets
Alluvium
deposits made by rivers and streams
Aluminosilicate minerals
minerals composed largely of oxygen combined with silicon but with some of the silicon
replaced by aluminum
colluvial deposits
soil or rock material gathered at the foot of a slope, primarily through the force of gravity
crystalline rocks
igneous and metamorphic rocks
Eolian deposit
materials deposited by wind
Hydrolysis
a chemical decomposition reaction in which a chemical bond is split and the elements
contained in water are added
Hydration
A mineral weathering process wherein water molecules combine with soil constituents
Igneous rock
a rock that formed by the cooling and solidification of liquid parts of the lithosphere
Loess
deposit of windblown soil particles, largely silt size
metamorphic rock
rock formed by recrystallization of igneous or sedimentary rock under great pressure
and heat whereby the minerals contained in the rock become reoriented
Oxidation
a mineral weathering process wherein oxygen ions combine with multivalent elements
such as iron, loss of electrons from an atom, molecule, anion, or cation
regolith
unconsolidated material above solid bedrock
sedimentary rock
a rock composed of sediment, that is, deposits made by water, wind, ice, and gravity
secondary mineral
a mineral formed by weathering from a primary mineral. For example, Kaolinite is a
secondary mineral formed from feldspar.
solum
The A and B horizons together or the single one of these that overlies the C horizon at a
site
fine earth
less than 2mm in diameter
sand, silt, and clay
major role in plant growth
