Which process primarily establishes soil profile horizons via pedogenesis?

💡 Explanation

Horizon segregation occurs via differential weathering; minerals weather at varied rates releasing ions. This initiates translocation due to leaching because chemical bonds break unevenly; therefore, layering arises rather than homogenous mixing expected from other depositional causes.
