← Earth & Natural SystemsWhat happens to the clay content of soil as the rate of hydrolysis of feldspar minerals increases during pedogenesis?
A)Clay content decreases initially
B)Clay content remains relatively stable
C)Clay content increases proportionally✓
D)Clay content fluctuates unpredictably
💡 Explanation
As hydrolysis of feldspar increases, it breaks down the feldspar mineral structure into clay minerals. The mechanism of chemical weathering via hydrolysis directly contributes to increased clay content because the feldspar minerals are converted into clay, rather than remaining unchanged or decreasing the amount of clay present.
