← GeographyWhich outcome occurs when parent rock weathers during pedogenesis?
A)Mineral composition of soil changes✓
B)Soil electrical conductivity decreases
C)Soil's thermal gradient reverses
D)Atmospheric pressure increases in pores
💡 Explanation
Weathering in pedogenesis facilitates mineral transformation in the soil through mineral dissolution; this is mineral alteration leading to changes in the soil's composition. Therefore, soil's mineral content changes rather than conductivity, temperature gradient, or pore pressures if weathering occurs in a regolith.
