As compared to subaerial basaltic lavas,submarine basaltic lavas differ in that they ____________.
A)always produce violent pyroclastic debris flows
B)produce large crystals of pyroxene and plagioclase
C)form pillow-like mounds because they cannot flow as far from their source
D)All of the above are correct.

Question

Quizplus · Accepted Answer

Submarine basaltic lavas cannot flow as far from their source due to the higher pressure and density of water, which causes them to quickly solidify and form pillow-like mounds. They do not typically produce violent pyroclastic debris flows, and while they may contain pyroxene and plagioclase crystals, they are not necessarily large. Therefore, choices A, B, and D are incorrect.
