Increased weathering rates occur in karst caves when?

💡 Explanation

Increased water CO2 concentration increases carbonic acid formation; this drives cave dissolution via dissolution weathering because the greater the chemical reaction, the more rock is dissolved. Therefore, more CO2 increases weathering, rather than diminished vegetation, higher rock strength, or increased air pressure.

• Which mechanism allows cave formation despite limited rainfall?
• Which geological outcome occurs when overlying clay restricts drainage in epikarst?
• Which outcome occurs when wave refraction focuses energy unevenly along headlands?
• Which outcome occurs from increased glacial meltwater streams?
• Which process causes seismic amplification when shear waves encounter a sedimentary basin bounded by a fault?
• Which outcome results when a rhyolitic lava dome undergoes rapid degassing?
