← GeographyWhich outcome results due to seasonal freeze-thaw in tundra?
A)Lobes of soil creep downhill✓
B)Accelerated chemical weathering of bedrock
C)Increased volcanic explosivity index
D)Significant rise in atmospheric methane
💡 Explanation
Solifluction, a type of soil creep, produces lobes of soil because repeated freeze-thaw cycles saturate the soil leading to downslope movement. Therefore, soil lobes form rather than accelerated weathering, which is more related to chemical processes.
