Definitions:

Volcanic Gas

Gases emitted from a volcano, including water vapor, carbon dioxide, sulfur dioxide, hydrogen sulfide, and other volcanic gases.

Convergent

Pertaining to areas where tectonic plates move towards each other, often resulting in mountain building or subduction.

Divergent

Relates to a tectonic boundary where two plates move away from each other, leading to the creation of new crust.

Transform

In geology, referring to a boundary between two tectonic plates where they slide past each other horizontally.
