When a material is melting, the temperature is likely to be increasing. That or the temperature is just above the material's melting/freezing point.
This is called the melting point, and the temperature is different for every material. For pure water, it is zero degrees Celsius, or 32 degrees Fahrenheit. Determining the melting point of any material is an important clue to determining what the material is.
The melting temperature of materials is affected by their confining pressure. The higher the pressure the higher the melting temperature. As such as you move deeper into the mantle, the tempraeture will increase, but because of the overlying material so to will the confining pressure which drives up the melting temperature. When high temperature mantle material moves nearer to the surface such as near a mid-ocean-ridge the confining pressure falls faster than the materials temperature and this can cause the melting point to drop below the temperature of the material leading to melting.

True
It causes a lowering of the melting temperature of the material, which in turn can cause partial melting of the mantle material leading to the formation of magma.
Celsius is a measure of temperature not a substance, and therefore it has no melting point. What is the melting point of what material in Celsius? [You haven't named the substance you want the melting point of/for]
This temperature is called melting point and is different for each substance or material.
Another name for freezing point is melting pointsince the temperature at which a substance freezes is also the temperature at which it melts, going in the other direction.Freezing point could also be referred to as congelation point.
there is a melting point of a bone and a bone can melt the melting point of a bone is at 1212 that is the melting point of the bone the material of the bones are easy to melt if your at the right temperature
The melting temperature of materials is affected by the pressure they are under. So when "rock" in the Earth's mantle experiences a decrease in confining pressure, not only does it expand, it's melting temperature drops. If the melting temperature of the material drops below the background (also known as the in-situ) temperature, then melting will occur and in this case magma will form.This typically occurs in the earth where hot upwelling mantle material experiences a decrease in confining pressure (as there is less and less overlying material as it rises) which ultimately causes adiabatic or decompression melting.
