Glacial till. Earth and rock materials picked up, mixed, crushed, transported, 

 and deposited by glacial ice. 



Gneiss. A crystalline rock in which the component minerals are arranged in 

 in parallel bands or layers. 



Granite. Light colored crystalline rock that is coarse grained and composed 

 mainly of quartz and feldspar. 



Horizon, soil. A layer of soil approximately parallel to the soil surface 

 with characteristics produced by soil-forming processes. 



Kame (geological). A short, irregular ridge of stratified glacial drift. 



Landscape. All the natural features such as fields, hills, forests, water, 

 etc, which distinguishes one part of the earth's surface from another. 



Mapping unit, soil. A soil phase, soil association, or other appropriate 

 unit shown on a soil map and identified by a numerical or letter symbol. 



Moraine, terminal. Earth and rock material moved by glaciers and deposited 

 at the farthest penetration of the ice sheet. 



Mottling, soil. Contrasting color patches that vary in number and size. 



Organic soil. A soil which contains a high percentage ( more than 20%) of 

 organic matter. 



Parent material. The imconsolidated mass of soil and rock material from 

 which the soil has formed. 



Permeability, That quality of the soil that enables water or air to move 

 through it. 



Phase, soil. A subdivision of soil series, based on features that affect its 

 management, but do not affect its classification, Textiire, steepness of 

 slope, number of rock outcrops, thickness of soil over parent material, and 

 natural drainage are examples of characteristics that suggest dividing a soil 

 into phases. 



Profile, soil. A verticle section of the soil through all its horizons and 

 extending into the parent material. 



Schist. A rock that has been highly altered by heat and pressure within the 

 earth's crust. It has parallel or foliated structure and cleaves rapidly. 



Sedimentary rock. A rock composed of particles- deposited in water and 

 cemented together. The principal groups are conglomerates (from gravels), 

 sandstones (from sand), and shales (from silts).
