Pahoehoe is a type of lava flow characterized by its smooth, ropy surface. It forms when low-viscosity basaltic lava erupts and cools slowly, allowing it to create a glossy, undulating texture. This type of lava is typically found in volcanic regions, such as the Hawaiian Islands, where it can spread over large areas. The name "pahoehoe" comes from the Hawaiian language, meaning "smooth" or "unbroken." Unlike Aa, another type of lava flow that is rough and jagged, pahoehoe flows are easier to walk on and can create unique formations like lava tubes and benches as they solidify.
