Which mechanism causes widening of cave passages following initial fissure formation?

💡 Explanation

Preferential flow path dissolution widens cave passages because water flow concentrates dissolution along existing weaknesses; therefore, passages expand rather than uniformly dissolving surrounding rock, because the concentrated flow enhances chemical weathering at specific sites.

• Which outcome results after permafrost degradation from solifluction?
• Which outcome occurs when rapid snowmelt increases stream discharge into glacial lakes?
• Which barometric outcome results if rising, saturated air reaches the tropopause and ascends no further?
