Question

Quizplus · Accepted Answer

Pyroclastic rocks are formed from volcanic materials ejected during explosive eruptions, such as ash and tuff. They are typically fragmental and extrusive, meaning they are formed from material that has been erupted onto the Earth's surface. Crystalline rocks are formed from cooling and solidification of magma or lava and have a distinct crystalline structure, while vitric rocks are formed from volcanic glass. Vesicular rocks have gas cavities (vesicles) within them, which can be present in any of the other types of igneous rocks. Therefore, the best choice for a fragmental, extrusive igneous rock is pyroclastic.
