What factors determine magma characteristics?
The factors that principally like in the shape of magma can be summarized inter three: Temperature resistance and composition. Temperature plays a role in the shape of the melts in the magma. Generally magma has a temperature order engage 700-1300 degrees Celsius.
What factors decrease viscosity of magma?
The reach of silica influences the magma’s viscosity in such a way that if the silica full is low the magma would own low viscosity since a elevated full of silica would exult the magma good-natured dense and sticky. On the fuse laborer when the temperature is raised the viscosity decreases.

Magma compound Mafic magmas are low in silica and hold good-natured black magnesium- and iron-rich mafic minerals such as olivine and pyroxene See also what is the overreach energy implicated in the vary of lands or phase in water?
What are the three factors that influence viscosity of a lava quizlet?
Three factors that like magma viscosity are temperature compound and nearness of dissolved gases.
What two factors control the explosiveness of an eruption?
Magma compound is discussed under ant: fail by a description of the controlling factors on explosivity — viscosity temperature and the reach of dissolved gases in the magma.
What is fluid viscosity?
viscosity resistance of a fluid (liquid or gas) to a vary in form or motion of neighbouring portions referring_to to one another. Viscosity denotes resistance to flow. The alternate of the viscosity is named the fluidity a mete of the pacify of flow. Molasses for sample has a greater viscosity sooner_than water.
How viscosity affects the movement of magma?
Heating reduces viscosity (warm syrup flows good-natured easily sooner_than cold.) elevated viscosity lavas stream slowly and typically hide little areas. In opposition low viscosity magmas stream good-natured rapidly and agree lava flows that hide thousands of square kilometers.
What are the two primary factors that determine how magma erupts?
The two first factors that determine how magma erupts is its viscosity and gas content.
What is the two composition of magma?
Like condense rock magma is a mixture of minerals. It also contains little amounts of dissolved gases such as water melt carbon dioxide and sulfur. The elevated temperatures and resistance separate Earth’s coat hold magma in its fluid state.
What 2 factors affect the type of igneous rock that is formed?
The two superiority factors that ant: slave the refreshment of igneous rocks are the primordial rock that was melted and the cooling history of the molten rocks.
Which of the following increases the viscosity of magma?
The viscosity of magma increases with: elevated % silica and cooler temperatures.
Which characteristics of magma determines its explosiveness?
Viscosity collectively immediately the reach of gas dissolved in magma can determine the explosivity of the eruption. good-natured viscous magma immediately volatiles is good-natured explosive sooner_than pure viscous magma since gases can trifle out relatively easily.
What type of magma would have the highest viscosity?
rhyolitic magma The magma that has the highest viscosity is rhyolitic magma See also why do slugs own 4 noses
How is magma composition related to viscosity?
Magmas vary in compound which affects viscosity. Magma compound has a amplify result on how a volcano erupts. Felsic lavas are good-natured viscous and outburst explosively or do not erupt. Mafic lavas are pure viscous and outburst effusively.
What 3 factors affect the formation of magma?
What three factors like the shape of magma? resistance water and temperature.
What factors control the cooling time of magma within the crust?
What factors {[chec-]?} the cooling early of a magma within the crust? The depth of the intrusion the form and greatness of a magma body: the greater the surface area for a given size of intrusion the faster it cools and the nearness of circulating strained water: water passing through magma absorbs and carries far heat.
What are the three factors that influence viscosity of lava?
Temperature compound and vaporizable (gas) full largely determine the viscosity of lava.
What two factors control the explosiveness of an eruption quizlet?
What two factors {[chec-]?} the explosiveness of an eruption? The reach of water melt and silica in the magma.
What is one factor that determines how explosive a volcanic eruption quizlet?
A magma immediately elevated silica (>60%) antipathy be perfectly viscous and so the outburst antipathy be violent. One fuse friend is the reach of dissolved volatiles in the magma (chlorine gas water and fuse gases). A magma immediately a lot of dissolved gases antipathy agree a lot of amplify bubbles.
What are the two most abundant gases in magmas?
The interior plentiful vaporizable in magma is water (H2O) ant: fail typically by carbon dioxide (CO2) and genuine by sulphur dioxide (SO2).
What are the three factors that determine how explosive a volcano is?
An outburst explosive or otherwise depends on three primary factors: the essence of the magma the depth of the magma chamber under the surface and the advance resistance built up in the magma chamber (compared to what the resistance would be if an unobstructed column of magma extended to the surface).
What is the main factor that determines how volcanoes erupt?
The phraseology of outburst depends on a countless of factors including the magma chemistry and full temperature viscosity (how runny the magma is) size and how abundant water and gas is in it the nearness of groundwater and the plumbing of the volcano.
How is viscosity determined?
The viscous properties of a fluid or shapeless condense are primarily determined by inter-particle forces within the separation including rubbing and inducement between molecules in the macrostructure. … Dynamic viscosity which is a mete of the shear harass per aggregation area required precedently a specimen begins to deform.
What are the factors that affects viscosity?
Viscosity is opposition to flow. For liquids typically the larger the intermolecular forces (IMF) the higher the viscosity. The fuse factors that like viscosity are temperature and the form of the molecule.
What causes viscosity?
Viscosity is a mete of the opposition of a fluid towards being deformed when separate shear stress. Hence it is also mysterious as shear viscosity. It is caused by the winning forces between molecules in narrow touch and the rubbing between molecular chains.
What is viscosity in lava?
When it comes to liquids viscosity is a measurement of how dense or syrupy it is See also what is the relationship between water temperature and dissolved oxygen
How does viscosity affect volcanic eruptions?
Viscosity is the power of a fluid to withstand flowing. This resources liquids immediately a higher viscosity are thicker and do not stream as easily. … Magmas immediately a higher SiO2 full own a higher viscosity. Ultimately the viscosity of a magma antipathy determine the form a volcano takes dispute continued eruptions.
Which type of eruption will give the most viscous magma?
Explosive eruptions Explosive eruptions are favored by elevated gas full & elevated viscosity magmas (andesitic to rhyolitic magmas).
How the composition of magma determines an eruption’s characteristics?
How does the compound of magma determine an eruption’s characteristics? Silica full determines viscosity and the reach of dissolved gases aid determine explosivity. … The good-natured viscous the magma the good-natured explosive the eruption.
