The porosity will vary with grain size in the following ways: a.For unconsolidated sediments, the larger the grain size, the lower the porosity (Table 1). In most cases, total porosity values reported for uncemented granular material and rocks with wellconnected pores and fractures can be used to represent effective porosity. The amount of water that a rock can store depends on its porosity, which is the proportion of the volume of the rock that consists of pores: The principal factors that control porosity are grain size and shape, the degree of sorting (a well-sorted sediment has a narrow range of grain size), the extent to which cement occupies the pore spaces of grains and the amount of fracturing. 5. change flow of water b) iron ore e) none of the above, c) waves can erode, deposit, or simply transport sediment, factors that affect the appearance of a shoreline include: b) shallow continental seas e) change their mineralogy, a) smaller and rounder as they are transported, When a plate boundary changes its orientation, it can change from: The water content in the soil at saturation is equal to the percent porosity .
