Sedimentary Rocks darkwing.uoregon.edu

Sedimentary rocks are classified in to three major categories based on the nature of the sediment. I. Detrital or Clastic Sediments These rocks are composed of fragments of pre-existing rock that have been eroded, transported and deposited in an accumulation that has subsequently been converted into a hard coherent sedimentary rock.

Alluvial Soil engineeringtraining.tpub

Alluvial Soil ALLUVIAL soil is formed when a soil- carrying stream gradually loses its carrying capacity with decreasing velocity. In slowing down, a river does not have sufficient power to keep the large particles of soil suspended; these particles settle to the riverbed. Further decrease in velocity causes smaller particles to settle.

Soils consist of grains (mineral grains, rock fragments, etc.) with water and air in the voids between grains. The water and air contents are readily changed by changes in conditions and location soils can be perfectly dry (have no water content) or be fully saturated (have no air content) or be partly saturated (with both air and water present).
