Why is it not possible to assign a melting temperature to a rock?

Rocks are combinations of minerals which have their own specific melting temperature. The variety of mineral compositions that are possible in a single rock type would make it hard to predict (without knowing the composition) when it would reach liquidus.

What determines a rock's melting point?
A rocks melting point would be determined by the highest temperature at which its constituent minerals would melt.
Does the temperature of the rock within the asthenosphere meet the melting point?
yes cuz its hot enuf
What rock needs melting then cooling?
An igneous rock
What stage in the rock cycle is between metamorphic rock and igneous rock?
Melting.
How does a metamorphic rock become an igneous rock?
by melting and cooling
How does water affect the melting temperature of rock at a convergent boundry?
Water reduces the melting point of rock.
If the temperature of rock rises above the melting point of the minerals the rock is composed of?
The rock will melt.
Which two factors affect the temperature that rocks melt at?
The two main factors that affect the temperature at which rocks melt are the composition of the rock and the pressure acting on it. Different minerals have different melting points, so the composition of the rock will determine its melting temperature. Additionally, pressure can increase or decrease the melting temperature of rocks, with higher pressure generally increasing melting temperature and lower pressure decreasing it.
Is pressure a contributor to a rock's melting temperature?

How does the presence of water affect the melting temperature of a rock?
The presence of water lowers the solidus temperature of rocks at a given pressure. It drastically changes the melting temperature by a vast amount.
How does the presence of water affect the melting temperature of rock?
The presence of water lowers the solidus temperature of rocks at a given pressure. It drastically changes the melting temperature by a vast amount.
When the temperature of rocks rises above its melting point?
If the temperature of rock rises above the melting point, it will melt into liquid. Theoretically, though not realistically, the rock could undergo a phase change and vaporize.
How does decreasing the pressure of the rock affect the temperature at which it melts?
Decreasing the pressure on rock will allow rock to melt at lower temperature. High pressures will raise the melting point of rock.
What happens when the temperature of rock rises above its melting point?
When the temperature of a rock rises above its melting point it turns into magma, usually found in the mantle (found below the Earth's crust).
Can you liquefy a rock?
Yes. Rock can be liquified by raising its temperature to that of the melting point of the mineral constituent with the highest melting point.
How can a rock that is above its melting temperature remain solid?
It can't. You can increase the melting point of a particular rock by placing it under a great deal of pressure however.
What affect does the presence of water have on the melting temperature of a rock?
Lowers the melting point. I know this because I am in Advanced Earth Science. :)
