2:! clays
Which of the following minerals is most soluble in a humid, temperate climate?
gypsum (soluble, often found in arid regions)
T/F: The surface area within a volume decreases as soil particles get bigger
, True
CEC
Cation Exchange Capacity: Soil's ability to absorb and release cations. A useful

Lacustrine
Marine
Glacial Till
Glacial Outwash
Alluvium
Water. a deposit of clay, silt, sand, and gravel left by flowing streams in a river valley or
delta, typically producing fertile soil.
Colluvium
Gravity. material that accumulates at the foot of a steep slope.
Residuum
formed in place from rocks. Only parent material that is not transported
Aeolian
Wind. Sandy/Silty, Blown into place
Lacustrine
Lake water. Deposition from lake water
Marine
Ocean. Sands/Clays deposition
Glacial Till
sediment deposited directly by a glacier
Glacial outwash
Sediment deposited by meltwater streams emanating from a glacier.
