Because it does. That's what the phase diagram for water looks like.
By the way, this is kind of a discredited notion. The freezing point is technically dependent on pressure, but it's a very small effect and isn't really going to matter much unless the temperature is very near the normal freezing point anyway.

What processes is most affected by pressure freezing or boiling or melting?
Boiling and freezing points of a substance are affected by pressure. An increase in pressure raises the boiling point and lowers the freezing point of a substance. Melting point is not significantly affected by pressure.
Does melting point depend on atmospheric pressure?
Yes, the melting point of a substance can be influenced by atmospheric pressure. In general, an increase in pressure raises the melting point of a substance, while a decrease in pressure lowers it. This is because pressure affects the equilibrium between the solid and liquid phases.
High pressure under skaters shoes lowers melting point of ice explain?
Under the pressure exerted by skates, the melting point of ice decreases due to the compression of the ice crystals. When pressure is applied, the ice molecules become more tightly packed together, causing a decrease in the amount of energy required for the molecules to transition from a solid to a liquid phase. This is why the pressure from skate blades can lead to the melting of ice beneath them, allowing for smooth gliding.
How is the melting point of asolid and boiling point of a liquidaffected when impurities are added to the substances?
Adding impurities lowers the melting point and raises the boiling point.
Does the presence of water raise the melting point of felsic magma?
No. Water lowers the melting point of magma, both mafic and felsic.

What do you think salt does to the melting point of ice?
Salt lowers the melting point of ice.

How does water affect the melting temperature of rock?
In theory yes: increasing pressure will increase the melting point mostly (not for ice!). In practice: it is hardly noticable, not significant at all, for most solid materials.Pressure increases the melting point of rock. The molecules are packed tighter together and thus take more energy to liquefy.
What lowers the melting point in alumina?
Cooling the heat source

No. Water lowers the melting point of magma, both mafic and felsic.
Why vacuum reduces melting point?
Reduced pressure in a vacuum lowers the boiling point of a substance by decreasing the pressure on the liquid, causing it to vaporize more easily. This leads to a decrease in the melting point as well, as the substance transitions from solid to liquid more readily in a vacuum environment.
What when applied to snow or ice lowers the melting point of the mixture?
Salt is commonly used to lower the melting point of snow or ice. When salt is applied, it disrupts the hydrogen bonds between water molecules, reducing the freezing point and causing the ice to melt even in subzero temperatures.
Why does salt prevent ice from forming on sidewalk?
salt lowers ice's melting point
What will be the melting point ice if it is kept under high pressure?
The melting point is not changed by pressure. It is still over 32O
