Feldspar weathers to form clay by the process of ____.
A) dissolution
B) hydrolysis
C) frost wedging
D) salt cracking

Question

Quizplus · Accepted Answer

Feldspar weathers by the process of hydrolysis, which involves the reaction between the mineral and water to form new minerals such as clay. Dissolution is the process of a mineral completely dissolving in water. Frost wedging is the physical weathering of rocks due to the expansion of water in cracks during freezing. Salt cracking is the weathering of rocks due to the growth of salt crystals in the pores of the rock. None of these processes directly lead to the formation of clay from feldspar.
