- 1The degree of acidity or alkalinity on a negative log scale of 1 to 14pH
- 2The breakdown of rock and mineral particles into smaller pieces by physical forces such as frost action and windphysical weathering
- 3The water content at which a soil will just begin to crumble when rolled into a thread approximately 3mm in diameter.plastic limit
- 4The part of the bulk volume of soil not occupied by soil particles. Also known as interstices or voids.pores
- 5The volume percentage of the total bulk not occupied by solid particlePorosity
- 6Clayey material having the tendency to change form a relatively stiff condition to a liquid mass when it is disturbedquick clay
- 7To fill all the voids between soil particles with liquid. To fill to capacity, as the adsorption complex with a cation species; for example H-saturatedsaturate
- 8A rock formed from materials deposited from suspension or precipitated from solution and usually more or less consolidated.sedimentary rock
- 91. A soil separate consisting of particles between 0.05 mm [.075 in engineering system] and 0.002mm in diameter. 2. A soil textural classsilt
- 10Any mineral occurring as part of or in the soil. A natural inorganic compound with definite physical, chemical and crystalline properties occurring in the soilsoil mineral
- 11The unconsolidated material on the immediate surface of the earth that serves as a natural medium for the growth of land plants.soil
- 12An equation relating to the terminal settling velocity of a smooth, rigid sphere in a viscous fluid of known density and viscosity to the diameter of the sphere when subjected to a known force field.Stoke's law
- 13The arrangement of sediments in layers or strata marked by a change in colour, texture, dimension of particles and composition.stratification
- 14A ridge-like accumulation of drift built chiefly along the terminal margin of a valley glacier or the margin of an ice sheet. It is mainly the result of deposition by ice, or formation by ice thrust, or bothterminal moraine
- 15The relative proportions of the various soil separates in a soil (clay, silt, sand and coarse fragments)texture
- 16The layer of soil moved in cultivation; the Ah horizon; presumably fertile soil material used to top-dress road banks, gardens and lawnstopsoil
- 17Elevation at which the pressure in the water is zero with respect to the atmospheric pressurewater table
