The temperature of the magma will affect its viscosity depending on its chemistry. Some minerals crystallize at higher temperatures than others, meaning that portions of the magma may have already solidified. At lower temperatures, the majority of the constituent minerals will have crystallized and solidified, leaving the magma highly viscous.
What else can I help you with?
What effect does silicia content have on the characteristics of magma?
Silica-rich magma is much more thick and viscous.
How do temperature pressure and fluid content affect the formation of magma?
The air affects magma. Once magma is released above ground, called lava, the air hardens it. While it is underground, the higher the temperature and pressure, the runnier the magma.
What affects the type of igneous rock that is formed?
Mineral composition of the magma, Rate of cooling of the magma, Temperature of the magma, Presence of volatiles and Amount of water present in the magma.
How do youCompute the partition coefficient in a magma?
The ratio of the concentration (by weight) of an element (e.g. Ti) in a crystallizing mineralto its concentration in the magma. For example, KTi = [Ti]min./[Ti]magma, where kTi is the partition coefficient for Ti, and [Ti]min. and [Ti]magma are the concentrations of Ti in the mineral and magma respectively. The value of k is dependent on temperature, pressure and the composition of crystallizing mineral and magma.
What three things determine how thick or thin magma is?
The three things that determine how thick or thin magma is temperature, silica content, and gas content.
What does the temperature have on the characteristics of magma?
Temperature, among other factors, effects the viscosity(thickness) of magma. However, for the most part, the temperature of magma is relatively consistent because magma is the type of molten rock that has not yet exited the volcano, so there are fewer factors to effect the temperature.
What temperature does magma solidify?
The composition of the magma effects the temperature it will cool and solidify at. In general most magma solidify at about 1,200 degrees Fahrenheit.
What term is used when describing characteristics of magma flow?
Rheology is the term used to describe the characteristics of magma flow, which includes its viscosity, temperature, pressure, and composition. These factors influence how magma moves and behaves beneath the Earth's surface.
What effect does temperature have on Characteristics of magma?
The temperature of the magma will affect its viscosity depending on its chemistry. Some minerals crystallize at higher temperatures than others, meaning that portions of the magma may have already solidified. At lower temperatures, the majority of the constituent minerals will have crystallized and solidified, leaving the magma highly viscous. F ME NIGars
What are the characteristics of magma associated with shield volcanoes?
Basaltic, runny magma.
How the minerals formed by magma?
Minerals are formed by magma through the process of crystallization. As magma cools and solidifies, the atoms and molecules within it arrange themselves into unique crystal structures to form various minerals. The specific mineral composition and characteristics depend on factors such as the temperature, pressure, and chemical elements present in the magma.
What effect does silica content on the characteristics 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!
Which is the most abundant in magma and has the greatest effect on its characteristics?
Silica is the most abundant component in magma and has the greatest effect on its characteristics. The amount of silica present determines the magma's viscosity, which in turn influences the explosiveness of volcanic eruptions.
What are some characteristics of the magma of a shield volcano?
Magma needs a some sort of level of silica and gas.
What effect does silicia content have on the characteristics of magma?
Silica-rich magma is much more thick and viscous.
How do temperature pressure and fluid content affect the formation of magma?
The air affects magma. Once magma is released above ground, called lava, the air hardens it. While it is underground, the higher the temperature and pressure, the runnier the magma.
Identify and explain the 3 factors that effect the force of a volcanic eruption?
The silica content effects the force of a volcanic eruption because magma with a lot of silica is thicker and magma with less silica is thinner. The amount of dissolved gases in magma effects the force of a volcanic eruption because the less gas in the magma, the less pressure will be inside the volcano. The temperature of the magma effects the force of a volcanic eruption because the hotter the magma, the more runny it is.
