________ Is A Major Dissolved Volatile Constituent In Both Magmas And Volcanic Gases.

Second, felsic magmas tend to have higher levels of volatiles; that is, components that behave as gases during volcanic eruptions. The most abundant volatile in magma is water (H2O), followed typically by carbon dioxide (CO2), and then by sulphur dioxide (SO2).

You are watching: ________ is a major dissolved volatile constituent in both magmas and volcanic gases.

Is the major dissolved gas in magmas?

When magma flows or erupts onto Earth’s surface, it is called lava. Like solid rock, magma is a mixture of minerals. It also contains small amounts of dissolved gases such as water vapor, carbon dioxide, and sulfur. The high temperatures and pressure under Earth’s crust keep magma in its fluid state.

Which of the following factors help determine whether a volcanic eruption will be violent or relatively quiescent quizlet?

What factors help determine whether a volcanic eruption will be violent or relatively quiescent? ___________tend to increase the explosive potential of a magma body beneath a volcano. High viscosity and high dissolved gas content. You just studied 17 terms!

What type of volcanic material is indicative of eruption under water?

Lava flows produced by eruptions under water are called pillow lavas. If the viscosity is high, but the gas content is low, then the lava will pile up over the vent to produce a lava dome or volcanic dome.

What are the three Vs of Volcanology?

Refers to the amount of magma being stored inside the volcano. In general, the more magma being stored, the hotter the conditions and the more violent the volcano. Refers to the amount of gases and water being stored within the magma of a volcano.

What are the two most abundant gases in magmas?

MAGMA COMPOSITION AND ROCK TYPES Because oxygen and silicon are by far the two most abundant elements in magma, it is convenient to describe the different magma types in terms of their silica content (SiO2).

How are most basaltic lava flows believed to form?

________ is a major dissolved volatile constituent in both magmas and volcanic gases. T/F: Most basaltic magmas are believed to form by partial melting of granite in the lower crust and upper mantle. Which type of basaltic lava flow has its surface covered with sharp-edged, angular blocks and rubble?
