What determines the severity of volcanic eruptions?
The size of the magma chamber and the viscosity of the magma.
What is magma mainly consisting of?
Magma consists mainly of molten rock with some dissolved gasses and sometimes crystallized minerals.
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!
Where does magma mainly rise to the surface?
at volcanoes
What determines the explosiveness of an eruption?
viscosity of magma build up of gases
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 size of a mineral crystal formed from magma?
The rate at which magma cools determines the size of the mineral crystal.
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 determines the size of a minerals crystals?
The rate at which magma cools determines the size of the mineral crystal.
What is magma mainly consisting of?
Magma consists mainly of molten rock with some dissolved gasses and sometimes crystallized minerals.
Which is not a characteristic of magma from an explosive eruption?
flows easily
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 mineral determines magma viscosity?
A magma's viscosity is directly related to its degree of silica content.
Where does magma mainly rise to the surface?
at volcanoes
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.
