Pahoehoe is a type of lava flow characterized by its smooth, ropy surface. It forms when low-viscosity basaltic lava cools and solidifies, allowing it to flow easily. The name "pahoehoe" comes from the Hawaiian language, meaning "smooth" or "unbroken." This type of lava can create unique formations, such as lava tubes and benches. Pahoehoe is often contrasted with aa, another type of lava flow that is rough and jagged. The differences in texture and appearance are due to variations in temperature, gas content, and flow rate. Pahoehoe flows can travel long distances, making them significant in volcanic landscapes.
