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 two components of magma?
Two primary components of magma are molten rock and dissolved gases. The molten rock consists of various minerals and elements, primarily silicon and oxygen, which form silicate materials. Dissolved gases, such as water vapor, carbon dioxide, and sulfur dioxide, can significantly influence the magma's viscosity and the nature of volcanic eruptions.
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 are the two types of magma?
The two main types of magma are mafic and felsic.

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.
