Weathered Earth materials blown away are called sediment, specifically aeolian sediment.

Here's a breakdown:

* Weathering: The process that breaks down rocks, soil, and minerals through physical and chemical processes.

* Sediment: The broken-down material from weathering.

* Aeolian: Relating to wind.

So, aeolian sediment refers to sediment transported and deposited by wind. Examples include:

* Sand dunes: Heaps of sand created by wind deposition.

* Loess: Fine-grained, wind-blown silt that forms thick deposits.

* Dust storms: Large amounts of fine sediment suspended in the air and transported by wind.
