2. Grain size distribution curves are illustrated below for four different soils. For each soil sample determine D10, D30, D50, D60, Cu, cc, %Gravel, %Sand, and %Fines. Also, if possible and appropriate, comment on the gradation characteristics of each sample (i.e. well, poor, uniform, etc.). Recall that you may not be able to determine D1o, D3o, and/or D6o for all of the samples. 100 -O- Soil 1 -- Soil 2 -Soil 3 Soil 4 90 0 80 0 70 60...

How does Physical Weathering change the chemical composition of a rock material? It creates new, different minerals from the old minerals It doesn't change the chemical composition of a rock material It dissolves soluble minerals, moving ions into solutions It relies on chemical reactions to break down the minerals In the ASCE or USBR Rock Weathering Descriptors, the description of "Moderately Severe" says that all (minerals) except quartz are discolored or stained, and that all feldspars are dull, discolored and...
