On the other hand, the small salt-poor particles form by homogenous nucleation directly from the gas phase.

The "salty" particles move slowly and mostly fall back onto the surface, while the fast "fresh" particles escape to the E-ring, explaining its salt-poor composition.

Dr. Denton, an internationally known authority on the biological role of salt, believes the human hunger for it arose early in hominid development as human ancestors evolved in salt-poor interior regions of Africa.

Euonymus europaeus (spindle, European spindle, common spindle) is a species of flowering plant in the family Celastraceae, native to much of Europe, where it inhabits the edges of forest, hedges and gentle slopes, tending to thrive on nutrient-rich, chalky and salt-poor soils.
