Which outcome occurs as basalt undergoes spheroidal chemical weathering?

💡 Explanation

Concentric layers form because chemical weathering attacks the sharp edges of the basalt boulder faster, a process called differential weathering; therefore, rind layers appear, rather than uniform degradation, because edges are less stable.
