Question

Quizplus · Accepted Answer

Igneous rocks formed by explosive volcanic activity have a pyroclastic texture, which means they are composed of fragments of volcanic material such as ash, pumice, and volcanic bombs that were ejected from the volcano during the explosive eruption. These fragments are welded together to form a solid rock. Aphanitic, porphyritic, glassy, and phaneritic textures are more commonly associated with volcanic or plutonic rocks that form through other processes.
