GEOLOGY

Detailed explanation-1: -Pahoehoe (pronounced pah-hoy-hoy) is a basaltic lava flow that has a smooth and twisty, rope-like surface. The characteristic ropy texture forms as the surface lava cools while the molten material beneath it is still moving.

Detailed explanation-2: -Lava flows Pahoehoe is lava that in solidified form is characterized by a smooth, billowy, or ropy surface, while aa is lava that has a rough, jagged, spiny, and generally clinkery surface.

Detailed explanation-3: -Pahoehoe lava flows are characterized by smooth, gently undulating, or broadly hummocky surfaces. The liquid lava flowing beneath a thin, still-plastic crust drags and wrinkles it into tapestry-like folds and rolls resembling twisted rope.

Detailed explanation-4: -Pahoehoe lava is characterized by a smooth, billowy, or ropy surface. Pahoehoe flows tend to be relatively thin, from a few inches to a few feet thick.

Detailed explanation-5: -The low velocity of pahoehoe flows means that the skin that forms by air-cooling is not disrupted during flow and can maintain its smooth, unbroken, well-insulating surface. Thus the temperature and viscosity of lava do not change very much even tens of kilometers from the vent.
