nationalgeographicmagazine: Pahoehoe Lava, Hawaii Photograph by Steve and Donna O’Meara, Volcano Watch International/National GeographicPahoehoe lava flows on Kilauea volcano in Hawaii Volcanoes National Park. Unlike aa (pronounced “ah ah”) lava, pahoehoe flows relatively slowly, allowing an insulating skin to form that keeps the temperature close to 2,190°F (about 1,200°C). Aa lava, on the other hand, moves faster and doesn’t have time to develop a skin, resulting in a cooler flow with a more angular texture. Buy This Photo
