Which outcome occurs when temperate forest leaf litter continually breaks down?

A)Increased soil Cation Exchange Capacity
B)Salinization of the A-Horizon increases
C)Reduced O-Horizon thickness is observed
D)Decreased mineral weathering rate occurs

💡 Explanation

Increased cation exchange capacity arises because pedogenesis in the A-horizon results from the constant decomposition of leaf litter; this outcome occurs during humification, a key process of pedogenesis, therefore higher organic content creates more exchange sites, rather than reduced CEC from mineral depletion.
