Which effect primarily shapes soil structure due to intensive earthworm activity?

💡 Explanation

The outcome is aggregate formation by bioturbation, because earthworm castings bind soil particles using digestive enzymes which therefore creates stable aggregates, rather than silica precipitation through weathering effects, related to chemical processes, or reduction of water related to arid region specific.
