How are scoria rocks formed

WebScoria is an extrusive igneous rock composed of highly vesicular volcanic glass, formed from violent eruption, depressurization, and rapid cooling of lava. It is almost always dark in color with a mafic or intermediate composition. Scoria is can be differentiated from pumice by its inability to float on water. Webscoria, heavy, dark-coloured, glassy, pyroclastic igneous rock that contains many vesicles (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 pahoehoe (smooth- or billowy-surfaced) lavas.
