Comparative Risk Assessment: Process that generally uses the judgement of experts to predict effects and set priorities among a wide range of environmental problems.
COMPACTION (SOILS)
Any process by which the soil grains are rearranged to decrease void space and bring them in closer contact with one another, thereby increasing the weight of solid material per unit of volume, ...
Soil Compaction Soil compaction refers to the formation of dense layers of well packed soil, often at the bottom of the cultivated layer.
Glacier - a large mass of ice formed, at least in part, on land by the compaction and re-crystallization of snow, moving by
creeping downslope or outward in all directions due to the stress of its own weight, and surviving from year to year.
These operations can reduce soil compaction by breaking up artificial hardpans and by incorporating organic matter into the soil, thereby reducing compaction and increasing moisture and nutrient holding capacity.
Glacier: A huge mass of ice, formed on land by the compaction and re-crystallization of snow, that moves very slowly downslope or outward due to its own weight.
Grab sample: A sample taken at a given place and time. Compare composite sample.
