Clay minerals, silica (SiO?), and dissolved potassium bicarbonate in the soil water are products of which process?
A)chemical weathering of olivine and plagioclase feldspar
B)mechanical weathering of granite and rhyolite
C)chemical weathering of orthoclase feldspar
D)differential mechanical weathering of micas

Question

Quizplus · Accepted Answer

Chemical weathering of orthoclase feldspar produces clay minerals, silica (SiO?), and dissolved potassium bicarbonate in the soil water. Choice A is incorrect because olivine and plagioclase feldspar weathering produces different products. Choice B is incorrect because mechanical weathering does not produce clay minerals and dissolved potassium bicarbonate. Choice D is incorrect because differential mechanical weathering of micas does not produce silica and dissolved potassium bicarbonate.
