It is where the liquid changes structure, liquid to gas, liquid to solid and such

Melting point and freezing point are at the same temperature, if you heat or cool the material slowly. If you do the heating/cooling rapidly, the material doesn't have time to do the transition evenly, and so you can get some super-heating or super-cooling.
Melting point is the temperature at which a material transitions from solid to liquid.
Freezing point is the temperature at which a material transitions from liquid to solid.
In both cases, the latent heat of fusion in involved. You have to add the latent heat of fusion (melting) to change from solid to liquid at the melting temperature. You have to remove the latent heat of fusion from the liquid in order to have it form the crystalline lattice of the solid form.

They both change the physical structure of the substance.
Melting point changes a solid to a liquid.
Freezing point changes a liquid to a solid.
Looks like I was too slow.

The substance changes form...from liquid to solid or from liquid to gas.
