Basaltic magma has longer chains of silicate tetrahedra than granitic magma allowing it to increase in velocity and this would cause basaltic volcanoes to erupt more violently than volcanoes with granite magma.

Question

Quizplus · Accepted Answer

This statement is false. Basaltic magma has shorter chains of silicate tetrahedra than granitic magma, which allows it to flow more easily and results in less violent eruptions. Granite magma has longer chains of silicate tetrahedra and is more viscous, resulting in more explosive eruptions.
