Quizplus · Accepted Answer

Basaltic magma is the most common type of magma on Earth and the most common magma that forms igneous rocks. Basaltic magma has a lower viscosity, which allows it to flow more easily and spread over larger areas. This results in larger volumes of basalt being produced compared to other types of magma.
