Which risk increases on a newly-formed volcanic island lacking vegetation?

💡 Explanation

Accelerated weathering occurs because little organic material buffers the newly exposed rock. Chemical weathering, rather than physical abrasion, becomes dominant; therefore, unstable volcanic minerals decompose at a high rate, unlike islands with pre-existing stable soils.
