← GeographyWhich risk increases when pyroclastic flows encounter saturated ground?
A)Enhanced lahar development downstream✓
B)Increased atmospheric methane production
C)Quicker solidification into welded tuff
D)Greater risk of volcanic landslides
💡 Explanation
Enhanced lahar development downstream increases because saturated ground incorporates easily into the pyroclastic flow via fluidization, creating a heavier, fast-moving mudflow. This increases lahar development further downstream when entrained, rather than directly producing landslides; these require distinct slope failures.
