A size term denoting particles, regardless of the mineral composition, with a diameter less than 2 microns.
100
What is Microorganism
An organism so small that it cannot be seen clearly without a microscope
100
What is Valley
An elongated depression between uplands, hills, or mountains.
200
What is Parent Material?
The horizon of weathered rock or partially weathered soil material from which the soil is formed.
200
What is addition?
Process of soil deposited due to erosion
200
What is Sand?
Textural class in which the particles are finer than gravel but coarser than silt, ranging in size from 2.00 to .5 millimeters in diameter.
200
What is leaching
The removal of soluble constituents from soils or other materials by percolating water
200
What is Translocation
To move or transfer from one place to another; cause to change location
300
What is Organic Matter?
Matter found in, or produced by, living animals and plants, which contains carbon, hydrogen, oxygen, and often nitrogen and sulfur.
300
What is Deposition?
The addition of sediment, as by flowing water
300
What is Silt?
Small, mineral, soil particle ranging in diameter from.5 to .002 millimeters.
300
What is Compaction
Decrease in volume of sediments, as a result of compressive stress, usually resulting from continued deposition above them.
300
What is Weathering?
Atmospheric action on rock surfaces producing composition, disintegration or alteration of rocks at close ti the earths surface.
400
What is Topography
Slope of the land and the position on the landscape, such as the top of a hill, a hillside, or the foot of a slope.
400
What is Reduction?
process of removing soil from the surface
400
What is Gravel
accumulation of water worn pebbles larger than two millimeters in diameter.
400
What is Irrigation
The artificial application of water to soil for the purpose of increasing plant production
400
What is Soil?
The mineral and organic surface of the earth capable of supporting upland plants. It has been and is still being formed by active factors of climate and biosphere exerting influences on passive parent materials and topography over neutral time.
500
What is Erosion?
The group of processes whereby earthy or rock material is worn away, loosened, or dissolved, and removed from any part of the earth's surface.
500
What is Transformation?
Change in form, appearance, nature, or character
500
What is Bedrock?
Unweathered hard rock that lies directly beneath the soil layers or beneath the superficial geological deposits, such as a glacial drift.
500
What is Mottle?
Color difference on a mass of moderately poorly drained soil
500
What is porosity
Refers to the extent of voids or openings in the soil that exists between soil particles and in clods. These pores hold water and air for absorption by plant roots
