Quizplus · Accepted Answer

A, B, and C are all terms used to describe the texture of igneous rocks based on the size and arrangement of mineral grains within the rock. Aphanitic describes a texture where the grains are too small to be seen by the naked eye, phaneritic describes a texture where the grains are visible, and porphyritic describes a texture where there are two distinct grain sizes present in the rock. Glassy, on the other hand, describes a texture where the rock is non-crystalline and appears like a solidified liquid or magma. Therefore, D is the option that does not fit the pattern.
