Match each weathering or mass wasting process listed on the left with its defining mechanism or physical movement characteristic on the right.
- CarbonationDissolution of calcium carbonate in limestone rocks by weak carbonic acid present in rainwater.
- HydrolysisChemical reaction where rock minerals absorb hydrogen ions from water, decomposing into clay minerals.
- SolifluctionSlow downslope flow of water-saturated soil and regolith over an impermeable permafrost layer.
- Soil CreepImperceptibly slow downslope movement of soil particles under gravity, evidenced by tilted telegraph poles.
Answer
Carbonation matches with the dissolution of limestone by carbonic acid; Hydrolysis matches with chemical alteration forming clay minerals; Solifluction matches with saturated soil flow over permafrost; Soil Creep matches with imperceptibly slow downslope movement causing tilted poles.
Each geographical process corresponds directly to its scientific mechanism: Carbonation dissolves calcium carbonate in limestone landscapes; Hydrolysis decomposes minerals into clay; Solifluction represents saturated soil flow over permafrost; Soil Creep is an ultra-slow downslope creep under gravity.
