Volcanoes with lower viscosity magma produce all of the following lavas except pahoehoe lapilli aa blocky

A. Pahoehoe

Explanation:

The flows of Pahoehoe are associated with slow effusion of eruptions that occurs at the volumetric and slow velocities. The low speed of Pahoehoe forms a cooling air which remains intact during the insulating surges. This increases the temperatures which ensure the viscosity of lava remains intact and too far ways from the tent.

The lava stops flowing and gets blown with while the eruption continues and cools down eventually between the toes.

polar areas, such as antarctica or the south pole.
