How do Martian dust storms mechanically contribute to maintaining the oxidized state of the surface material?

Fine particles have a higher surface area, making them exponentially more reactive to oxidizers

The dust that causes global dust storms plays an active role in sustaining the oxidized appearance of Mars through mechanical weathering. Wind action grinds stable, oxidized rocks into fine dust particles. These micro-sized particles possess a significantly higher surface area relative to their volume compared to solid bedrock. This increased surface area means they are exponentially more susceptible and reactive to any remaining atmospheric oxidizers or sunlight exposure. Therefore, the constant mobilization and suspension of this fine dust continuously accelerates the chemical weathering process, acting as a feedback loop that maintains the oxidized state of the surface material.
