Line 4:
In the Southern hemisphere, both of the current models for this part of the process involve liquid water. In one of these models the features from initially as fresh water at 0 °C below clear ice in a solid state greenhouse effect, picking up salts as they start to flow outwards.
In the northern hemisphere then most of the models also involve water, but one model has dry ice and cascading sand instead. The northern hemisphere flow like features form at much lower surface temperatures and if they involve brines the temperatures are around -90 °C.
The southern hemisphere Richardson crater flow-like features are the ones of most interest for potentially habitable brines.
