Rhymes with SCORIA


noun    (Concise Encyclopedia)

Heavy, dark, glassy igneous rock that contains many bubblelike cavities. 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 lavas. Other scoria, sometimes called volcanic cinder, resembles clinkers, or cinders from a coal furnace.
