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.
A rocks melting point would be determined by the highest temperature at which its constituent minerals would melt.
yes cuz its hot enuf

by melting and cooling
Water reduces the melting point of rock.
The limiting factors for maximum temperatures in metamorphism are the geothermal gradient (rate of temperature increase with depth), pressure, and the melting temperature of the rock minerals. Exceeding these limits can lead to melting and formation of igneous rocks.
The presence of water can lower the melting temperature of a rock by facilitating the movement of ions and promoting the process of melting. Water reduces the viscosity of molten rock, making it easier for the rock to melt at lower temperatures.
The rock will melt.
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.

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.
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 a rock rises above its melting point it turns into magma, usually found in the mantle (found below the Earth's crust).
It can't. You can increase the melting point of a particular rock by placing it under a great deal of pressure however.
Each rock has a specific melting point or a range of temperature when the the rock is thermally decomposed.
True. A wet rock generally melts at a lower temperature than a dry rock because the presence of water in the rock lowers its melting point due to the water acting as a flux, reducing the energy required for melting.
