According to the Udden-Wentworth scale, gravel can be divided into pebbles ranging in size from 4 mm to 64 mm (0.2 to 2.5 inches) or granules with particles ranging from 2 mm to 4 mm (0.079 to 0.157 inches). Subcategories of granular gravel are fine and very fine.cobble, and boulder gravel, rock outcrops, and shell beds, among others.

A ternary diagram is used to translate a sediment's proportion of the three different classes of grain size—sand, silt, and clay—into a soil description. To the geologist, sand is material with grain sizes between 2 millimeters and 1/16th millimeter; silt is 1/16th to 1/256th millimeter; clay is everything smaller ...2.2.4 Grain Size Distribution Real rocks contain a distribution of grain sizes, and often the grain size distribution is multi-modal. The best way of understanding the effect is to consider the variable admixture of grains of two sizes (Figure 2.4). The porosity of the mixture of grain sizes is reduced below that for 100% of each size.cobble, and boulder gravel, rock outcrops, and shell beds, among others.
