Which long-term consequence occurs when volcanic tephra increases?

💡 Explanation

Enhanced silicate rock chemical weathering results because tephra increases reactive surface area, therefore accelerating chemical reactions rather than decreasing weathering from inert aerosol-induced albedo change or affecting oceanic productivity.
