← GeographyAfter a large volcanic eruption deposits thick tephra layers, which landform change mechanism accelerates?
A)Increased surface runoff erosion✓
B)Accelerated chemical weathering rates
C)Glacial ice accumulation increase
D)Formation of deflation hollows
💡 Explanation
Land denudation accelerates because tephra isn't cohesive; it increases surface runoff causing increased overland flow and channel erosion, therefore increasing surface runoff rather than chemical weathering (slower), glacial activity (unrelated), or wind deflation (less impactful).
