Which horizon-forming outcome intensifies with increased cryoturbation in tundra soils?

💡 Explanation

Intensified cryoturbation accelerates organic matter translocation within the soil profile because freeze-thaw cycles churn layers into new formations via pedogenesis. Therefore, options A; rather than B,C,D, which cryogenic action impedes due water displacement that reduces chemical effectiveness by volumetric reduction.

• Which outcome occurs when increased thermal expansion weakens the temperature gradient along Arctic river outflow streams?
• Which outcome occurs when magma cools rapidly within a volcanic vent of a lava dome?
• Which outcome occurs when a significant amount of water is carried into the mantle by a subducting slab?
• Which mechanism causes effusive lava flows to transition into more explosive eruptions as silica content increases in a volcano?
• Which phenomenon impacts regional climate when subduction introduces water into Earth's mantle?
• Which geomorphic risk is most amplified when infrastructure development disrupts thermokarst processes within permafrost regions?
