READING VOCABULARY
Alluvial Soil – soil that has been transported in suspension by flowing water and subsequently deposited by sedimentation.
Colluvial Soil – soil transported downhill by gravity, such as by landslides or creep.
Organic Soil – soil with a high organic content, normally greater than 25% by weight. In general, organic soils are highly compressible and have poor load-sustaining properties..
Remolded Soil – soil that has had its natural structure modified by mechanical manipulation
Residual Soil – soil found in place, formed by weathering of the underlying material.
Clay Soil – fine-grained soil finer than 0.002 mm (0.005 mm in some cases) that exhibits plasticity with a range of water contents. It usually exhibits considerable strength depending on the presence of other soil materials when air-dried.
