What are your choices

mafic(besaltic)magma

The type of magma that flows very fast is called basaltic magma. It is low in viscosity, which means it is relatively thin and fluid. Basaltic magma has a low silica content and is rich in iron and magnesium. This composition allows it to flow easily and relatively quickly compared to other types of magma.

If you wanted to find this information on your own, you can start by researching different types of magma. One key characteristic to look for is magma viscosity, which determines how easily it can flow. Basaltic magma is known to have low viscosity, making it a good candidate for fast-flowing magma. Additionally, examining the composition of different types of magma can also give you an idea of their flow properties. Researching the composition of basaltic magma will lead you to its low silica content and high iron and magnesium content, which contribute to its ability to flow rapidly. By digging into these factors, you can identify basaltic magma as the type that flows very fast.
