Question

Quizplus · Accepted Answer

The two most abundant gases in magmas are water vapor and carbon dioxide. This is because magmas are primarily made up of silicate minerals, which contain trapped volatiles such as water and carbon dioxide. When the magma reaches the surface and erupts, these gases are released into the atmosphere and can contribute to volcanic hazards such as ashfall and lava flows. The other options listed are not commonly found in magmas.
