Final answer:

The term for clay and silt particles deposited by the wind is 'loess'. It is a fine-grained sediment that can eventually become a type of sedimentary rock. Loess is part of the soil and is transported and deposited by wind after weathering of rocks.

Step-by-step explanation:

The term for particles of clay and silt that are eroded and deposited by the wind is Loess. Loess is a type of sediment that is composed of very fine particles of clay and silt that are easily transported by wind. It is commonly found in desert and coastal regions and is typically red in color.

Loess is a fine-grained, unstratified accumulation of clay and silt which has been deposited by the wind. Over time, sedimentary rocks such as loess can also form from the compaction of these particles. The soil is part of the Earth's outer loose layer that covers its surface, with a vertical section known as the soil profile. The soil particles have various sizes, with clay having the smallest particles and silt being slightly larger. The silt soil particles range in diameter from 0.002 to 0.1 mm. Through chemical and physical weathering, pre-existing rocks break down, resulting in these particles of different sizes, such as sand, silt, and clay, which can then be transported by elements like wind.
