Conceptual animation depicting how geochemical processes during the course of Mars' history may have produced the methane plumes now seen in Mars' atmosphere. Here, through a process called serpentinization, methane is generated as part of a reaction involving the conversion of liquid water (seen seeping into the planet's crust), iron oxide, and carbon dioxide energized by the planet's internal heat into serpentine minerals.
