Which outcome occurs when basaltic lava exhibits pahoehoe flow?

💡 Explanation

Smooth, ropy surfaces result because pahoehoe flows exhibit Surface Tension effects, retaining heat and pliability, therefore forming curved shapes, rather than fragmenting like blocky flows, which radiate heat faster due to their higher surface area.
