Which outcome occurs when vegetation cover declines, impacting exposed shale bedrock?

💡 Explanation

Declining vegetation exposes soil which reduces carbon inputs and therefore the Accumulation of Soil Organic Matter decreases via reduced bioturbation, rather than faster rock formation, or altered weathering of stable rock structures.
