Which one of the following processes leads to expansion of certain minerals as they take up water, causing additional stress in the rock ?
General KnowledgeGeography
- AHydrolysis
- BHydration
- COxidation
- DCarbonation
Explanation
Hydration is the chemical weathering process in which minerals absorb water and expand, creating internal stress that disintegrates rock. Hydrolysis, oxidation and carbonation do not involve such expansion by water uptake. Hence the process is hydration.
