Slow downslope flow of saturated unfrozen earth materials. The presence of a frozen substrate, or even freezing and thawing is not implied in the original definition (Andersson, 1906). However, one co
mponent of Solifluction can be the Creep of Frozen Ground. Rates of flow vary widely. The term is commonly applied to processes operating in both Seasonal Frost and Permafrost areas. Solifluction in Permafrost is commonly referred to as Gelifluction.
An isolated, tongue-shaped solifluction feature, up to 25 m wide and 150 m or more long, formed by more rapid solifluction on certain sections of a slope showing variations in gradient
A point on the ecliptic where the Sun reaches its greatest absolute declination. There are two of these points, halfway between the equinoxes; they mark the beginning of summer and winter.
Either of the two points on the ecliptic at which the apparent longitude of the Sun is 90° or 270°. Also the time at which the Sun is at either point. Solstices occur when the Earth's axis is oriented
directly toward or away from the Sun, causing the Sun to reach its northernmost and southernmost extremes.
The total amount of solute species that will remain indefinitely in a solution maintained at constant temperature and pressure in contact with the solid crystals from which the solutes were derived.
