The two main gases dissolved in magma are water vapor (H₂O) and carbon dioxide (CO₂). These gases play a crucial role in the behavior of magma, influencing its viscosity and the explosiveness of volcanic eruptions. As magma rises toward the surface, the decrease in pressure allows these gases to escape, which can lead to the formation of bubbles and explosive activity. Other gases, such as sulfur dioxide (SO₂) and nitrogen (N₂), may also be present but in smaller quantities.

What are the two factors the control whether a volcano eruption will be explosive or quiet?
The two main factors that control whether a volcano eruption will be explosive or quiet are the viscosity of the magma and the presence of dissolved gases. High viscosity magma (thick and sticky) and high gas content tend to result in explosive eruptions, whereas low viscosity magma (thin and runny) and low gas content lead to quiet eruptions.
What are 2 factor that determine the degree of violence with which a volcano erupts?
Two key factors that determine the degree of violence in a volcanic eruption are magma viscosity and gas content. High-viscosity magma, such as that rich in silica, tends to trap gases, leading to increased pressure and more explosive eruptions. Conversely, low-viscosity magma allows gases to escape more freely, resulting in less violent eruptions. Additionally, the amount of dissolved gases, such as water vapor and carbon dioxide, influences the eruption's explosiveness.
What two things determine the viscosity of magma?
The viscosity of magma is primarily determined by its composition and temperature. Higher silica content increases viscosity, making the magma thicker, while lower temperatures also contribute to greater viscosity. Conversely, magma with lower silica content and higher temperatures tends to be more fluid. Additionally, the presence of dissolved gases can influence viscosity by reducing inter-particle friction.
The two major dissolved gases in ocean water are?
The two major dissolved gases in ocean water are oxygen and carbon dioxide. Oxygen is essential for marine life to respire, while carbon dioxide plays a role in the ocean's carbon cycle and influences seawater acidity levels.
What factors determine if a volcanic eruption will be quite or explosive?
The two main factors are the viscosity and the gas content of the magma. explosive eruptions usually occur when magma approaches the surface and dissolved gasses bubble out so rapidly that it escapes explosively, creating clouds of ash and pumice. If there isn't enough gas this can't happen. High viscosity magma by definition does not flow easily. This allows pressure to build inside or under a volcano as the magma moves slowly. The higher viscosity also means the magma can hold more gas.

What are the two types of magma?
The two main types of magma are mafic and felsic.
Name two dissolved gases which are carried by the blood?

What two things does the appearance of a volcano depend on?
One factor that influences a volcanic eruption is the composition of the lava; the thicker the lava, the more explosive the eruption. Another factor is the level of pressure that forces magma up a pipe or vent; the higher the pressure, the more violent the eruption.

What 3 factors determine magma viscosity?
The three elements that determine viscosity in magma are:TemperatureSilicaOxides (gases)Viscosity changes the way in which magma will flow. Magma with low viscosity will flow much more easily than high viscosity magma.

The two major dissolved gases in ocean water are oxygen and carbon dioxide. Oxygen is essential for marine life to respire, while carbon dioxide plays a role in the ocean's carbon cycle and influences seawater acidity levels.
Which are the two main gases?
Hydrogen and Helium
What are the common gases in the galaxy?
Hydrogen and helium are the two main gases in the Universe.
What two gases are vital to marine life?
Gases are also dissolved by seawater. Carbon dioxide(CO2) is dissolved in ocean water and used by phytoplankton to produce plant matter. Oxygen and nitrogendissolved at the surface from the atmosphere are also present in seawater. Conversely, the ocean also releases these gases into the atmosphere.
