What are 3 substances that affect the explosiveness of volcanic eruptions?
Amount of dissolved gasses in a liquid, the silica content, and the viscosity of the magma.
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.
Dissolved minerals trapped in magma under tremendous pressure provide the force for a volcanic eruption?
No. Dissolved gasses trapped under pressure provide the force.
Can 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?
False

Which of the following is associated with mid ocean ridges?
Volcanic structures
True or False Dissolved minerals trapped in magma under tremendous pressure provide the force for a volcanic eruption?
False
Which of the following is true about volcanic eruptions?
Volcanic eruptions act as constructive forces when lava builds up to form volcanoes and plateaus.
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.
Which of the following can lead to areas of frequent volcanic eruptions?
The movement of tectonic plates
Which of the following is an interaction between the earths interior and atmosphere and surface?
a volcanic erruption
How does volcanic ash form?
Volcanic ash forms as a result of gas trapped in magma. As the magma approaches the surface and pressure drops, the gas is released and expands violently. The explosion blasts the magma into small particles, which become volcanic ash.
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.
