Which soil horizon develops rapidly when vegetation cover expands?

💡 Explanation

Rapid expansion of vegetation generates substantial leaf litter causing rapid development of Horizon O. Increased organic deposition drives pedogenesis because decomposed organic matter is concentrated at the surface, therefore Horizon O forms rapidly, rather than mineral-rich lower horizons.
