Final answer:
The most abundant gases typically released during volcanism are water vapor and carbon dioxide.
Step-by-step explanation:
The gases that are typically released during volcanism are water vapor and carbon dioxide.
Volcanoes emit large amounts of water vapor, which is released from magma as steam. This is often the most abundant gas released during volcanic eruptions.
In addition to water vapor, volcanoes also release carbon dioxide. This gas is a greenhouse gas, meaning it can trap heat in the atmosphere and contribute to climate change.
