The explosiveness of magma is primarily determined by its viscosity, which is influenced by its chemical composition, particularly the silica content. High-silica magma tends to be more viscous, trapping gas bubbles and increasing pressure until explosive eruptions occur. In contrast, low-silica magma is less viscous, allowing gases to escape more easily and resulting in less explosive eruptions. Thus, viscosity plays a crucial role in the behavior of volcanic eruptions.
The size of the magma chamber and the viscosity of the magma.
Magma is mainly consisting of molten rock, which is a mixture of solid minerals, gases, and liquid rock. The composition of magma can vary depending on factors such as depth, temperature, and the geological setting.
Silica is something in the magma, so it is a pretty important part of magma because it pretty much a part that makes magma!
viscosity of magma build up of gases
Viscosity is the measure of a liquids resistance to flow. In the case of magma, the hotter it is, the lower the viscosity.
The rate of cooling of the magma determines the type of mineral formed by the magma or lava..

The size of the magma chamber and the viscosity of the magma.
A magma's viscosity is directly related to its degree of silica content.
magma that is low in silica and flows easily
The rate at which magma cools determines the size of the mineral crystal.
