________ is a felsic igneous rock with a meringuelike vesicular texture, consisting of very small holes, created by small shards of volcanic glass.

C)Granite
D)Pumice

Question

Quizplus · Accepted Answer

The description given in the question matches the characteristics of Pumice, which is a felsic igneous rock with a vesicular texture due to the presence of small, evenly distributed holes or vesicles created by the rapid cooling and depressurization of the magma. Scoria is also a vesicular igneous rock, but it is typically darker and more dense than pumice. Obsidian is a volcanic glass, without any crystalline structure, and therefore does not have a vesicular texture. Granite is a plutonic igneous rock with a phaneritic texture, composed of interlocking minerals, and therefore is not a suitable choice for the given description.
