- 1Glacial DriftRock material carried by glacial ice or glacial meltwater
- 2Glacial TillUnstratified glacial drift carried by glacial ice
- 3Glaciofluvial DepositsMaterial moved by glaciers and subsequently sorted by rivers
- 4Ground MoraineUnsorted mixture but predominately till
- 5HorizonLayer of soil approximately parallel to land surface
- 6Hydraulic ConductivityProportionality factor in Darcy's Law applied to water flow in a soil
- 7Hydraulic HeadElevation with respect to specified reference level at which water stands in a piezometer connected to said point
- 8Hydrologic CycleConditions that water naturally passes through from time of precipitation until it returns to atmosphere
- 9infiltration RateSoil characteristic determining/describing maximum rate at which water can enter the soil, under certain conditions, including excess water
- 10Inorganic SoilA soil made up mainly of mineral particles (<17% carbon)
- 11IonAtom, group of atoms, or compound that is charged due to a loss or gain of electrons
- 12KameIrregular ridge or hill of stratified glacial drift left by meltwater
- 13KettleDepression left after the melting og a detached mass of glacier ice buried by drift
- 14Lacustrine DepositMaterial deposited in lake water and later exposed by water level decline or land rising, mostly clay and sand
- 15LiquificationSudden, large decrease of shearing resistance of cohesionless soil
- 16Liquid LimitWater content corresponding to an arbitrary limit between liquid and plasic states,
- 17LoessMaterial transported/deposited by wind, primarily silt
- 18MarlA soft, unconsolidated earthy deposit consisting of;
calcium carbonate or magneseum carbonate, or both;
Often contains shells and clay - 19Mass WastingVariety of processes by which large masses of earth material are moved by gravity
- 20Metamorphic RockRock derived from preexisting rocks through heat and pressure
- 21MineralHomogeneous naturally occurring phase, sometime restricted to inorganic, crystalline phases
- 22MontmorilloniteSpecific aluminous member of the smectite group
i.e. Expanding clay - 23MoraineAccumulation of earth, generally stones, left by glacier
- 24Parent RockRock in which the parent materials of soils are formed
- 25Particle Size AnalysisDetermination of the amount of varying soil seperates in a soil sample;
Sedimentation, sieving, or micrometry - 26Particle Size DistrublutionAmounts of various soil separates usually expressed in weight percentages
- 27Perched Water TableWater table due to 'perching' of water on a relative impermeable layer at some depth in soil
- 28PercolationDownward movement of water through soil; specifically in saturated or nearly saturated soil
- 29PermafrostPerennially frozen material underlying the solum. A frozen soil horizon. Perennially.
