The pahoehoe flow has a comparatively smooth or "ropy" surface. The surface of the aa flow consists of free chunks of very angular pieces of lava. This difference in form reflects flow dynamics. Aa forms when lava flows rapidly.

Answer: b. Fast-moving, hot lava.

Explanation:

  • A lava flow is the outpouring of the lava which is formed due to a non-explosive eruption which is effusive in nature.
  • The word Pahoehoe is derived from a Hawaiian word which means smooth and unbroken.
  • Pahoehoe is a type of lava flow which is fast-moving and hot.
  • This type of lava flow is characterized by low viscosity and a smooth flow which looks like rope coils.
