pa·hoe·hoe

(pə-hoi′hoi′, pə-hō′ĕ-hō′ĕ)
Lava with a smooth, swirled surface. It is highly fluid and spreads out in shiny sheets. Compare aa. See Table at rock.
Word History The islands that make up Hawaii were born and bred from volcanoes that rose up over thousands of years from the sea floor. Volcanoes are such an important part of the Hawaiian landscape and environment that the people who originally settled Hawaii, the Polynesians, worshiped a special volcano goddess, Pele. Not surprisingly, two words have entered English from Hawaiian that are used by scientists in naming different kinds of lava flows. One, pahoehoe, refers to lava with a smooth, shiny, or swirled surface and comes from the Hawaiian verb hoe, "to paddle" (since paddles make swirls in the water). The other, aa, refers to lava having a rough surface and comes from the Hawaiian word meaning "to burn."

Basaltic flows that have erupted at low effusion rates or while still hot near their vents have smooth, folded surfaces with a texture called pahoehoe (a Hawaiian word), the result of plastic stretching of the outer skin as the lava advances; at higher effusion rates, or at lower temperatures farther from the vent, the surface fractures in a more brittle fashion to produce a very rough texture called 'a'a.
