Because the melting/freezing point is the point at which the particles in a substance begin to go through the phase change
so for example at 0 degree's Celsius water starts to freeze, but at the same time also melts, its sorta like some of the particles are freezing while the others are melting at the same time, but if you go above 0 degrees then it melts, and if you go below it freezes
Explanation:
There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus. Because plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds. Dandelion seeds float away in the wind
Movement of lithospheric plates created isolation between populations and with isolation comes different mutations and lineages which is how evolution occurs. (This is called allopatric speciation!).
