Which of the following is a true statement about lava that contains large amounts of dissolved gases? Lava that produces violent
anygoal [31]

<u>Answer:</u>

<em>The dissolved gases produce violent eruption as they escape. </em>

<u>Explanation:</u>

Magma contains dissolved gases and these dissolved gases induce vapor <em>pressure on the magma.</em> The magma is able to remain in the dissolved state itself without erupting because this vapor pressure is less than the confining pressure of the <em>rock surrounding the magma. </em>

One the vapor pressure exceeds this confining pressure the dissolved gases begin to  expand and<em> forms small gas bubbles</em>.

The <em>density of these gas bubbles</em> called vesicles is less than the density of magma and thus naturally tries to push out. When the gas bubbles escape the magma is also pushed out. Thus greater <em>amount of dissolved gases result in violent eruptions. </em>
