How does a solid become a liquid (freezing)

All substances have something called (melting point) when the solids get the temperature of the melting point it becomes liquid. for water, the temperature needs to be over 0°c so it can melt .what is happening is that the atoms become excited by the rise in the temperature atoms start moving around faster and push away from near atoms. If their melting point were lower will be liquids when the temperature is above 0°c  we see the (freezing or freezing point) the temperature in which a liquid becomes solid. when the molecules lose energy a liquid cools its particles slower and come closer together

Ex
Ice
Snow
Liquid hydro
Etc
