Which horizon change occurs when intense rainfall enhances leaching?

💡 Explanation

Enhanced rainfall causes increased mobilization of humus within the A horizon, reducing organic content because eluviation preferentially removes it rather than depositing it; therefore, the A horizon loses organic matter, rather than its enrichment, or impacts to zones below it.
