What determines the severity of volcanic eruptions?
The size of the magma chamber and the viscosity of the magma.
What effects does silica content have on the characteristic of magma?
Silica is something in the magma, so it is a pretty important part of magma because it pretty much a part that makes magma!
What is magma mainly consisting of?
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.
What determines the explosiveness of an eruption?
viscosity of magma build up of gases
What determines how different types of volcanos are created?
The formation and composition of the magma, and the local subterranean geology.
What mainly determines the viscosity of a magma?
Viscosity is the measure of a liquids resistance to flow. In the case of magma, the hotter it is, the lower the viscosity.
What determines the type of mineral formed by cooling magma?
The rate of cooling of the magma determines the type of mineral formed by the magma or lava..
What determines the severity of volcanic eruptions?
The size of the magma chamber and the viscosity of the magma.
Which is characteristic of the magma that formed the Hawaiian islands?
magma that is low in silica and flows easily
What mineral determines magma viscosity?
Silica is the mineral that determines magma viscosity. Magma with high silica content tends to be more viscous, leading to slower flow and potentially more explosive volcanic eruptions.
What determines the size of a minerals crystals?
The rate at which magma cools determines the size of the mineral crystal.
Which is not a characteristic of magma from an explosive eruption?
flows easily

What is magma mainly consisting of?
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.
What determines the magnetism of rocks formed from cooling magma?
The composition of the magma and the local magnetic flux as it crossed the Curie point.
What determines the explosiveness of an eruption?
viscosity of magma build up of gases
What determines the size of a mineral crystal formed from magma?
The cooling rate of the magma primarily determines the size of a mineral crystal. Faster cooling rates lead to smaller crystals, while slower cooling rates result in larger crystals. Other factors such as the mineral composition and level of nucleation can also influence crystal size.
