The picture below shows a soil texture triangle. Soil texture triangle. Clay soil is approximately 45 percent or less sand, 50 percent or more clay, and 40 percent or less silt. Silty loam soil is approximately 50 percent or less sand, 30 percent or less clay, and 50 percent or more silt. Sandy clay soil is approximately 45 to 65 percent sand, 35 to 55 percent clay, and 25 percent or less silt. Sandy clay loam soil is approximately 45 to 80 percent sand, 20 to 35 percent clay, and 35 percent or less silt. Based on the soil texture triangle, how much sand is present in silt? 0 percent to 10 percent 20 percent to 40 percent 40 percent to 60 percent 60 percent to 80 percent Question 17(Multiple Choice Worth 1 points) [RM.04]Which of these Earth spheres interact when glaciers carry the top soil from one place to another? atmosphere and geosphere atmosphere and hydrosphere cryosphere and geosphere cryosphere and hydrosphere Question 18(Multiple Choice Worth 1 points) [RM.04] The pictures below represent three soil profiles. Three images shown in a row, showing various soil profiles. Profile A (the one on the far left) shows plants at the top with one fairly uniform layer of larger rocks beneath. Profile B (in the middle) shows plants at the top with three distinct layers. The top layer is very granular, the middle layer is medium sized rocks and the bottom layer is larger rocks. Profile C (the one on the far right) shows plants growing on top of two distinct layers. The top layer is very granular and the lower level is made up of large rocks. Which of these statements is correct about the soil profiles? Profile A is formed after Profile B. Profile B is formed after Profile C. Profile A and Profile B are formed before Profile C. Profile B and Profile C are formed before Profile A. Question 19(Multiple Choice Worth 1 points) [RM.04]Which of these is most likely a step in the formation of soil? erosion of soil crystallization of rocks animals digging rocks solidification of organic matter Questio
