1. Soils can be formed from the weathering of rocks and the decay of organic matter. List the three (3) main groups of rocks that we discussed in class. 2. In nature, soil is often transported by various means to other sites. List the four (4) main categories of transported soil deposits that we discussed in class. 3. A sample of soil has a total weight (W) of 1.2 lbs. The weight of the water (Ww) in the soil sample is 0.5 lbs. If air is considered as having no weight (WA=0 lbs.) then the weight of the voids in the soil sample (Wv) is how many lbs? 4. A sample of soil has a total weight (W) of 1 lb. The weight of the water (Ww) in the soil is 0.25 lbs. If air is considered as having no weight (WA=0 lbs.) then the weight of the solids in the soil sample (Ws) is how many lbs? 5. An empty container has a mass of 21 grams. A wet soil sample is put in the container and together they weigh 150 grams. The container with wet soil sample is dried in the oven and then the container with the now dried soil is put on the scale again and it together they weigh 119 grams. Calculate the moisture content (w) of the soil. Show your calculations. 6. A soil sample with a total volume (V) of 1 ft³ has a void ratio (e) of 0.56 and a water content (w) of 15%. The volume of the solids (Vs) is 0.64 ft³. The weight of the solids in the soil sample is 105.4 lbs. The weight of the water in the soil sample is 15.81 lbs. Neatly draw a block diagram, calculate all missing values of volume and weight and label all values of volume and weight on the block diagram. Hint: Remember that the unit weight of water is a constant. 7. Calculate the unit weight of this soil sample. 8. Calculate the dry unit weight of this soil sample. 9. Calculate the porosity of this soil sample. 10. Calculate the degree of saturation of this soil sample.
