Compare: Both are caused by movement of one medium over the rock surface.
Contrast: Glacial abrasion is slower, but more certain. Wind abrasion may be faster, but depends on entrained particles.

Explanation:

A glacier provides its own abrasion material and force in the form of heavy solid ice. Additional material carried along with it just increases the effectiveness.

While winds may create some erosion from their own force displacing small granules of rock, most of the real abrasion from "wind" is caused by the small particles of matter - some of it rock - that are carried in the wind and impact on fresh rock surfaces.
