Answer
Some loess deposits are related to glaciers through the process of glacial flour production. As glaciers advance, they grind and pulverize rocks beneath them, producing a fine, dusty sediment known as glacial flour. When the glaciers retreat, this glacial flour is exposed to the wind, which can carry it over long distances and deposit it as loess. Thus, loess deposits associated with glaciers are formed from the fine-grained particles created by glacial erosion and then transported and accumulated by wind action.
