Websediment will affect the proportion of void spaces and are related to porosity (n). Porosity can be defined as a measure of the volume of particles contained in a given volume of space. Tightly packed, well-rounded sediment for example will have a lower porosity when compared with a more loosely packed, irregularly shaped sediment mix. WebAttrition is the process of erosion that occurs during rock collision and transportation. The transportation of sediment chips and smooths the surfaces of bedrock; this can be through water or wind. Rocks undergoing attrition erosion are often found on or near the bed of a stream. Attrition is also partially responsible for turning boulders into smaller rocks and … WebAlthough it does not make up substantial sediment thicknesses in the geologic record, till makes a discontinuous cover for as much as 30% of the earth's continental landmasses and forms significant deposits in Precambrian and Permo-Carboniferous rocks of South America, Africa, and North America (Fig 2).Till consists of unsorted, unstratifiedpebbles, … red hat oke
