Water vapor is a major dissolved volatile constituent in both magmas and volcanic gases.

What are 3 substances that affect the explosiveness of volcanic eruptions?
Water, gas content, and silica content are three substances that can affect the explosiveness of volcanic eruptions. Higher water content can generate more explosive eruptions, whereas higher gas content and higher silica content can also contribute to increased explosiveness.
Which factors help determine whether a volcanic eruption will be explosive or relatively quiet?
The volatile content of the magma. Weather water or Ice has ingres to the volcanic vent. The physical stability of the volcano.
What is Meaning of explosively unstable?
It means something is highly volatile and likely to explode or change very quickly and uncontrollably.
Dissolved minerals trapped in magma under tremendous pressure provide the force for a volcanic eruption?
No. Dissolved gasses trapped under pressure provide the force.
True or False Dissolved minerals trapped in magma under tremendous pressure provide the force for a volcanic eruption?
True. The dissolved minerals trapped in magma create gases that are released under pressure, causing the magma to rise and eventually leading to a volcanic eruption.

No. Dissolved gasses trapped under pressure provide the force.
Which ONE of the following is NOT one of the sources of dissolved salts in seawater?
Rainfall is NOT one of the sources of dissolved salts in seawater. Salt in seawater comes from the erosion of rocks on land, underwater volcanic activity, and the release of minerals from hydrothermal vents.
What is the gas that is erupted by volcanoes that combines with oxygen in the air to form hot water vapor or steam?
Hydrogen is a minor constituent of volcanic gas. This will burn in air to form water vapor. However, volcanic gas also includes water vapor anyway.
Is a cauldron like volcanic feature usually formed by the collapse of land following a volcanic eruption?
No, a cauldron is typically formed by the collapse of a volcanic crater following a volcanic eruption. It is a depression in the earth's surface that can be caused by the emptying of a magma chamber beneath the volcano.
Which of the following can lead to areas of frequent volcanic eruptions?
The movement of tectonic plates
What happens when Magma with a large amount of dissolved gases tends to be?
When magma with a large amount of dissolved gases reaches the Earth's surface, the gases expand rapidly, causing pressure to build up. This can lead to explosive volcanic eruptions as the built-up pressure is released violently, ejecting magma, gases, and volcanic ash into the air.
Why does a quiet volcanic eruption form lava sheets?
less gas dissolved in the ejected material therefore less ash ad explosiveness in the eruption. There still is an outpouring of matter though in the form of lava with less dissolved gas.
