Hole: GEOS 2104 Study Aid M-1 Soil, Erosion Soil what is a soil scientist’s definition of
soil
: what does a geologist call that? what is a soil engineer’s definition of
soil
: what does a geologist call that? what is a geologist’s definition of
soil
: what process creates soil? (topic of previous lecture) what are the two possible geologic parent materials
? define consolidated
(geologist’s definition): what does a soil engineer mean by “
consolidated
”?
Hole: GEOS 2104 Study Aid M-2 Soil, Erosion define leaching
: how is it similar to metasomatism
(metamorphic lecture)
? what happens to the solid being leached? what happens to the water? how are weathering and leaching related? what are the two main zones in soil formed by leaching? which is shallower & which deeper? number the materials in order, from most likely to be leached to least likely: by what processes? clay Fe, Al oxides organic material quartz soluble minerals
Hole: GEOS 2104 Study Aid M-3 Soil, Erosion number the materials in order, from most likely to be re-
deposited deeper in the soil to least likely: processes
? clay Fe, Al oxides organic material quartz soluble minerals define the primary soil layers: (connect these “layers” to the two “zones” on the previous page) layer A
: define: materials present: colours: how long to create after destroyed? layer B
: define: materials present:

Hole: GEOS 2104 Study Aid M-4 Soil, Erosion layer B
: colours: how long to create after destroyed? layer C
: define what happens to rainforest soil fertility if you cut down the vegetation? what can destroy soil? (2 ways; both discussed elsewhere in course
) what 5 factors affect the type of soil created? explain how 1) 2)
Hole: GEOS 2104 Study Aid M-5 Soil, Erosion 3) where is the USA warmer, colder? where is the USA wet, moist, dry? 4) 5) define an ultisol
soil (
the most common soil in Virginia
): where in VA? where in USA? which of the 5 factors (previous page) most control its development?
Hole: GEOS 2104 Study Aid M-6 Soil, Erosion define an alfisol
soil where in VA? where in USA? which of the 5 factors (previous page) most control its development? define an inceptisol
soil where in VA? where in USA? which of the 5 factors (previous page) most control its development? define an entisol

Hole: GEOS 2104 Study Aid M-7 Soil, Erosion define a histosol
soil where in VA? where in USA? which of the 5 factors (previous pages) most control its development? clay
: reminder: what shape & size of crystals? reminder: what process creates it? what special electrical property? usually strong or weak? role in liquefaction? high or low permeability?
Hole: GEOS 2104 Study Aid M-8 Soil, Erosion define permeability
: why is clay’s permeability important to humans (2 major reasons)? what happens when water is added to clay? describe expansive
soils describe compressible
soils how does clay affect soil fertility?
Hole: GEOS 2104 Study Aid M-9 Soil, Erosion Erosion reminder: define erosion
: (
from sedimentary and weathering lectures
) what does the erosion? what factors increase erosion by water? processes? what factors increase erosion by wind? processes?
