Question

Item 4 4 of 14 rock components and alters mineral constituents. n both weathering types, water plays a major role in rock breakdown, but moreso in chemical weathering. For instance, chemical weathering needs water to act as a solvent and to transport corrosive ions. Hence, in arid and arctic climates (where water is typically not available or frozen) chemical weathering processes are restricted. Chemical processes are also (mostly) accelerated by higher temperature, so the high humidity and high temperature of the tropics make it a the place where chemical weathering predominates. Both composition and rock characteristics can influence how fast or slow a rock will weather chemically. A silicate mineral's resistivity to weathering correlates to its order of formation in Bowen's reaction series. Silicate minerals that crystallize early (e.g., olivine) are least resistant to weathering, whereas silicate minerals that crystallize late (e.g., quartz) are most resistant. Additionally, a rock with cracks and/or holes is more susceptible to chemical weathering Part A Read the following descriptions of several different environments. Based on the information given, sort each environment into the correct bin for an environment that would experience predominantly mechanical weathering or predominantly chemical weathering. Drag the appropriate items into their respective bins. View Available Hint(s)
