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.
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 causes a volcano to be explosive?
When the vocano is dormant ( not active ) for some time a crust forms ovdr the top of the volcano which has lava inside. When it becomes active then the pressure keeps building up and after some time it can't take any more and blows the crust off causing the lava and tiny crust rocks,gas and ashes to comne flying out.
What are the two main gases produced by the industrial gases industry?
The two main gases produced by the industrial gases industry are oxygen and nitrogen. These gases have a wide range of applications in various industries including healthcare, manufacturing, and electronics.
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?
one of them is oxygen
What are the two main gases in theatmosphere?
The two main gases in the Earth's atmosphere are nitrogen (about 78%) and oxygen (about 21%).
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?
Temperature: Higher temperatures result in lower viscosity since the magma is more fluid. Composition: Silica content influences viscosity, with higher silica content leading to higher viscosity. Gas content: Higher gas content increases viscosity as gas bubbles create resistance to flow.
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.
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 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.

What gas is dissolved in acid rain that causes it to be acidic?
Two gases are the main cause of acidic rain. Sulfurdioxide (SO2) is a gas that is converted into Sulfuric acid (H2SO4) in the air. Another gas is NO2 (nitrogendioxide) which is converted into Nitric acid (HNO3) in the air.
