Which process dominates mineral soil formation during pedogenesis?

💡 Explanation

Chemical weathering dominates mineral soil formation during pedogenesis because hydrolysis, oxidation, and carbonation reactions break down rocks; therefore, smaller mineral particles form, rather than larger clasts accumulating via erosion, or solely from from bioturbation or organic deposition.

• Which process initiates enhanced glacial erosion and cirque formation in arctic mountains subject to freeze-thaw cycles?
• Which atmospheric phenomenon is intensified by extensive tephra emission?
• Which increasing risk to alpine communities results when permafrost thaw amplifies seismic ground motion?
• Which outcome will accelerate barrier island erosion when longshore drift weakens?
• Which outcome occurs when permafrost thaw increases rates of pedogenesis?
• Which effect primarily results when coastal upwelling significantly diminishes due to weakened trade winds?
