which of the following does not affect the viscosity of magma?

Which of the following does not have an impact on the degree to which magma flows? Temperature Silica Content Amount of gas Temperature Silica Content There is not the slightest change in the magma’s consistency due to any of them.

 

When magma is cooled, its viscosity changes, but how exactly does this occur?

When lava is allowed to cool, its viscosity undergoes a number of changes. As the temperature drops, it becomes more prevalent… Magma that has a high percentage of silica has a viscosity that is either greater or lower than magma that contains a low percentage of silica. A greater amount of silica contributes to the increased viscosity of magma.

When magma becomes more solid, what happens to its viscosity?

In other words, the magma’s viscosity will grow as it cools down. Crystallization of magma, which takes place when temperature drops, results in an increase in this attribute. In conclusion, the make-up of a magma has a significant impact on the viscosity of the magma. When there is a larger percentage of silica, the resulting magma is more acidic and more viscous.

What kind of an effect does magma’s temperature have on its viscosity?

MAGMA’S VISCOSITY AT CERTAIN TEMPERATURES AND THE AMOUNT OF GAS PRESENT… It should come as no surprise that temperature has an influence on viscosity. Just with the majority of liquids, the viscosity of a material will decrease as its temperature increases since it will become more fluid. When it comes to defining a magma’s viscosity, composition plays an even more important impact.

Does Magma That Has Been Cooled Down Flow More Rapidly Or Slower?

According to the laws of thermodynamics, the flow of colder magma is often slower than the flow of hotter magma. This holds true for the majority of things on our world.

What Occurs When Magma Cools Answer to the Short Question?

Igneous rocks are formed when the components contained inside magma mix and crystallize into minerals during the cooling process of magma. Magma may either cool off under the surface or on the surface itself (magma that reaches the surface is called lava). Igneous rock is generated when magma solidifies into rock over time.

What Takes Place When the Temperature of the Magma Falls?

The temperature of the magma begins to decrease as it loses heat to the rocks that surround it, and as a result, things begin to change. When combined, silicon and oxygen produce the tetrahedral structure known as silica. As the tetrahedra continue to cool, they begin to fuse together into chains, a process known as polymerization. The lava becomes more viscous due to the presence of these silica chains.

In what ways does the viscosity of the magma affect the explosive potential?

A magma that is thicker and more viscous will result in a more powerful volcanic explosion. The amount of silica present in the magma is one factor that plays a role in determining this. Magma that has less than 45 percent silica will have a fluid consistency, and as a result, the eruption will not be explosive. … Magma that has less than 45 percent silica will have a fluid consistency, and as a result, the eruption will not be explosive.

Why does a higher temperature cause a magma’s viscosity to decrease while the temperature stays the same?

Why does a higher temperature cause a magma's viscosity to decrease while the temperature stays the same?
Why does a higher temperature cause a magma’s viscosity to decrease while the temperature stays the same?

The viscosity of the liquid is said to decrease as the temperature rises since the flow rate increases. When it is heated, the liquid does not resist being moved. The quantity of silica (sand) in the magma has a direct correlation to the viscosity of the magma… The viscosity of a liquid is reduced in proportion to the increased proportion of water present in the liquid.

What Causes an Increase in the Magma’s Viscosity?

The higher the percentage of silica in magma and the lower the temperature, the higher the magma’s viscosity. Plutonic rocks are those that are created when magma cools and solidifies deep inside the crust without exploding. Magma that is very thick (viscous) has a greater chance of staying buried under the surface.

What are the factors that contribute to magma’s low viscosity?

The viscosity of lava is mostly determined by its temperature, composition, and the amount of volatile (gas) content. The viscosity of the lava is reduced as it is heated to a higher temperature (the thinner it is). When lava is cooled, its viscosity increases, and vice versa (the thicker it is).

What factors influence the rate at which magma and lava cool?

When magma is contained underground in an igneous intrusion, it gradually cools because it is shielded from the air and other rocks by the intrusion itself. Crystals are given a longer period of time to grow to their full size. Rocks with a grain size somewhere in the middle are created by minor intrusions like sills and dykes (crystals 2mm to 5 mm).

When the lava is allowed to cool, what happens to it?

When the lava is allowed to cool, it solidifies into rock. The lava that emerges from volcanoes in Hawaii has a highly fluid consistency… When it does erupt, the volcano will sometimes send fragments of rock and ash flying into the air. The ash and the hardened lava both contribute to the formation of more precipitous volcanoes.

How does the lava get less hot?

Lava isn’t a very good heat conductor, thus it takes a long time for it to cool down under the crust on the surface. In addition, the insulating qualities of lava lead it to cool at an ever-increasingly gradual rate over time. Lava flows that are piled up to a height of 30 meters (or 100 feet) might take years to fully calm off.

What Occurs When the Molten Rock Condenses?

Lava is the term used to describe magma that has made its way to the surface of the earth. After it has cooled and become more brittle, igneous rock will have been formed. The process by which igneous rock is created on the surface of the earth is referred to as extrusive.

Which of the following forms does magma transform into when it is allowed to cool?

rocks formed by magma
When lava is allowed to cool, it undergoes a similar transformation to that of molten rock, becoming a solid known as rock. Igneous rocks are rocks that are formed when lava cools down and solidifies into rock. One kind of igneous rock is formed when magma cools at a rapid rate, whereas another type is formed when magma cools at a slower rate.

What Phenomenon Occurs When Magma Condenses And Becomes Solid?

Igneous rock is the name given to the rock that is formed by the solidification of lava as it cools. Igneous rock may take on a wide range of morphologies and chemical make-ups, all of which are dependent on the conditions of its birthplace and the pace at which it cools. The final product of full crystallization is a solid mass consisting of crystals of varying sizes that are interlocked with one another.

If the magma’s temperature continues to rise, its viscosity will continue to increase as well.

If the magma's temperature continues to rise, its viscosity will continue to increase as well.
If the magma’s temperature continues to rise, its viscosity will continue to increase as well.

magma’s degree of viscosity The composition of the magma as well as its temperature both have a role in the flow resistance. A larger percentage of silica results in a greater degree of viscosity. But at lower temperatures and with a smaller gas component, the viscosity will be greater. Therefore, a magma with a lower viscosity and a lower gas concentration will have a greater temperature.

What Does Magma’s Viscosity Look Like?

Magnitude of Magma’s Viscosity
Viscosity may be defined as the flow resistance of a fluid (opposite of fluidity). The temperature and the chemical make-up of the magma are the two primary factors that determine the magma’s viscosity. Magmas with a greater silica (SiO2) content have a higher viscosity than magmas with a lower silica (SiO2) content (viscosity increases with increasing SiO2 concentration in the magma).

What Happens To Magma After It Is Heated Up Deep Within the Earth?

Additionally, decompression melting takes place at mantle plumes, which are columns of hot rock that ascend from the higher-pressure core of the earth to the lower-pressure crust of the earth. When they are found below the ocean’s surface, these plumes, which are also known as hot spots, force magma up onto the seabed… The heat from the liquid rock is transferred to the crust that is around it when it solidifies.

What exactly is meant by the term “viscosity,” and what is the connection between this term and the manner in which a volcano erupts?

In addition to this, the viscosity of the lava may also be measured. The size and form of a volcano are both determined by the viscosity of the lava within. In spite of the fact that it is 100,000 times more viscous than water, lava is nonetheless capable of flowing across significant distances. When the viscosity of the lava is low, it is able to flow extremely freely across very large distances.

To What Extent Does Each Of These Three Factors Influence The Magma’s Viscosity?

Temperature, the amount of dissolved gases the lava contains, and the chemical make-up of the lava are the three parameters that have the most impact on the lava’s viscosity.

Which kind of magma is responsible for the most violent eruptions?

Magmas with a high gas concentration and a high viscosity are more likely to produce explosive eruptions (andesitic to rhyolitic magmas).

What are the two most important factors that contribute to the magma’s viscosity?

The amount of silica in a magma as well as its temperature both have an effect on its viscosity. If there is a low concentration of silica in the magma, then the magma will have a low viscosity. On the other hand, if there is a high concentration of silica in the magma, then the magma will be more viscous and sticky.

What Causes Viscous Magma to Activate?

Temperature, composition, and the existence of dissolved gases are three elements that have a role in determining the viscosity of magma.

When the temperature is high, what kind of an effect does it have on the viscosity?

At higher temperatures, the viscosity of gases rises while the viscosity of liquids decreases; thus, the drag force also increases.

Which of the following parameters has the greatest impact on magma’s degree of viscosity?

Temperature, composition, and the existence of dissolved gases are three elements that have a role in determining the viscosity of magma.

Which of the following would cause the magma to have a greater degree of viscosity?

The lava with the maximum viscosity would have both a high silica concentration and a high temperature. This would be the case for all of the following.

What Effects Does the Viscosity of Magma Have on the Topographic Profile of a Volcano?

The lava is able to go down hill on a mild slope because the magma has a low viscosity, but as it cools and its viscosity grows, its thickness builds up on the lower slopes, giving them a slightly steeper gradient. When seen from above, most shield volcanoes have a form that is generally round or oval.

What is the relationship between the composition of magma and its viscosity?

The many components that make up magmas each have their own unique viscosity. The make-up of the magma has a significant bearing on the manner in which a volcano erupts. Felsic lavas are more viscous than other types of lavas and either explode violently or do not erupt at all. The viscosity of mafic lavas is lower, and their eruptions are more effusive.

What factors have an impact on magma’s thickness and viscosity?

Abstract. In general, the thickness of a lava flow is determined by three aspects: the viscosity of the lava that is flowing, the angle of slope of the surface over which the lava is flowing, and the local topography, which refers to whether or not the lava is ponded in a depression.

Does the presence of water change the viscosity of magma?

The presence of water lowers the viscosity of magma, which refers to the degree to which a liquid is thick or thin.
