Key for Problem Set #2 1. Match each type of parent material with its appropriate mode(s) of origin. a. Alluvium flowing water /sorted b. Colluvium gravity/very poorly to non-sorted c. Residium none: this parent material forms in place, it is not transported d. Lacustrine lake water/sorted e. Marine ocean water/sorted f. Till moving ice/non-sorted g. Loess wind / sorted 2. Would a soil tend to develop faster in glacial till or bedrock, everything else being equal? Provide two reasons why? Glacial till would be faster: it is already experienced a high degree of physical weathering. Thus, it has a high surface area for chemical weathering and it is permeable (higher porosity) allowing water to flow through it to enhance chemical weathering, translocation and leaching. Bedrock would have to physically breakdown first before any appreciable weathering, translocation or leaching could take place. 3. How could you visually distinguish whether a rock is granite or basalt? List two clues that could help you make this decision. Color - granite is light colored due to the abundance of quartz and feldspars which are
