When generating granite from basalt via crystal fractionation we would need approximately ____ of basalt for every km of granite produced.
A)½ cubic km
B)1 cubic km
C)5 cubic km
D)10 cubic km

Question

Quizplus · Accepted Answer

Granite is less dense than basalt, meaning that to generate a given volume of granite, a larger volume of basalt is required. The process of crystal fractionation, where different minerals crystallize at different temperatures, leads to the concentration of silica and the formation of granite from basalt. It is estimated that about 10 cubic kilometers of basalt are needed to produce 1 cubic kilometer of granite through this process.
