Quizplus · Accepted Answer

The unit composed of volcanic blocks and volcanic ash is characteristic of a pyroclastic eruption, which involves explosive ejection of fragments of rock and lava into the air that fall to the ground and form layers of volcanic ash and blocks. Basaltic flows and pahoehoe lava are typically composed of fluid lava that spreads over the ground, while a lava fountain involves the ejection of molten lava into the air without the formation of solid fragments.
