Question
Match the sedimentary environments with the sediment deposited in each: 1. Point bar of a meandering stream 2. Braided glacial outwash stream bar 3. Base of a rock cliff above tree line 4. Shallow restricted ocean basin/ arid climate 5. Across the floodplain of a river a) halite b) course gravel c) mud d) angular boulders e) sand 6-9. arrange these minerals from least to most stable under chemical weathering: a) k-feldspar d) olivine b) quartz 7) c) pyroxene least stable 6) 8)-- 9)most stable Circle the best single answer. 10. The climatic conditions that favor the highest rates of chemical weathering: a) cold and dry b) hot and wet c) warm and dry d) cold and wet e) hot and dry 11. The products of weathering that are not transported away from the site of weathering: a) glacial outwash b) sediment c) regolith and soil d) point bar e) alluvial fanExplanation / Answer
6-9) From leasst stable to most stable minerals are i) Olivine (Least stable) ii) Pyroxene iii) K-feldsper iv) Quartz (Most stable)
10. Highest rate of chemical weathering environment occured in hot and wet climates. Because chemical weathering is the chemical reactions between minerals in rocks and external agents like air or water that breaking down of rocks, soil, and minerals. Oxygen oxidizes minerals to alteration products whereas water can convert minerals to clays or dissolve minerals completely.
11. The products of weathering that are not transported away from the site of weathering is regolith and soil.
