Tangential sorting is the result of sediment being deposited in same direction as flow. Normal tangential sorting results in a gradient of sediment sizes deposited from largest to finest as they travel downstream. When sediments are deposited from smallest to largest as they travel downstream, this

In reference to windblown sediment, a wide range of conditions such as distance and height of transport and varying wind patterns at the sediment source can affect grain size, rate of transport and distribution of sediment. Windblown sediment travels one of three ways--rolling,

that is reworked by fluvial processes tends to have more poorly sorted sediment as compared to sediment sorted by only
Aeolian processes because loess particles become mixed with preexisting sediment of varying grain sizes within bodies of water.
