Foamlike scoria, in which the bubbles are very thin shells of solidified basaltic magma, occurs as a product of explosive eruptions (as on Hawaii) and as frothy crusts on some pahoehoe (smooth- or billowy-surfaced) lavas. Scoria forms outside of the volcano when the lava flow becomes frothy on top then cools quickly. This rock is often called “lava rock” and is popular as landscape mulch.
