Which outcome occurs when slow lava flow cools?

💡 Explanation

Block lava forms because the lava's high viscosity prevents smooth flow during cooling, resulting in a fractured surface, therefore a mass of detached blocks is produced, rather than forming smooth pahoehoe or highly fragmented aa textures.
