Answer:
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.
