It arises, or emerges, or "pops through" only when water molecules engage in morphodynamic relationships at cold temperatures.
浮力这个新性质只有当水分子们在低温下卷入到形态动力学关系中以后，才会产生，或出现，或突然蹦出来。

The long-term morphodynamic model is used to simulate morphologic evolution process in a long time scale, its key is to define the model representative input condition.
Emergent properties arising via thermodynamic and morphodynamic constraints are abundant in non-life: the hardness of minerals; the malleability of metals; the surface tension of liquids.
