How does ash reach ice?

Ash can reach ice primarily through atmospheric processes. When volcanic eruptions occur, ash is released into the atmosphere and can be transported by winds over long distances. If these ash particles settle on ice, they can darken the surface, reducing its albedo and causing it to absorb more sunlight, which can lead to accelerated melting. Additionally, ash can also be deposited on glaciers and ice caps, contributing to changes in their surface characteristics and melting rates.
