← GeographyWhich outcome results when intense chemical weathering alters feldspar?
A)Formation of secondary clay minerals✓
B)Increased soil organic carbon content
C)Accelerated rate of glacial retreat
D)Decreased atmospheric carbon sequestration
💡 Explanation
Intense chemical weathering decomposes feldspar via hydrolysis, leading to the *neoformation* of clay minerals such as kaolinite, rather than increasing organic matter or affecting global climate phenomena, because the alumina and silica combine into crystalline clay structures. Therefore, clays form.
