Which type of magma may be unable to form a volcanoes

Andesitic or basaltic magmas may be unable to form volcanoes.

Explanation:

For the magma to form a volcano, it is required that the magma has a substantially high content of gas and highly viscous molten or semi-molten material. Neither andesitic nor basaltic magma contains high gas content or highly viscous material. This makes them incapable of erupting or exploding. Rather, these magmas form creeks and flow out of them like fluid and spread on the adjacent ground.
