Rocks can melt at different temperatures depending on their composition. For example, most igneous rocks melt between 600°C and 1,300°C, while some metamorphic rocks can melt at temperatures above 700°C. Additionally, the presence of water and other minerals can influence the melting point of rocks.

Why metamorphic rock will form neither synthetically nor naturally if the temperature is too high?
If the temperature is too high, the rock will melt into magma and form igneous rock instead of metamorphic rock. Metamorphic rocks form under high pressure and temperature conditions, but if the temperature becomes too high, the rock will not be able to maintain its solid state and 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.
How does decreasing the pressure of the rock affect the temperature at which it melts?
Decreasing pressure lowers the melting point of rocks because it reduces the confining pressure that keeps the rock in a solid state. As pressure decreases, the rock requires less energy to overcome the intermolecular forces holding its crystal lattice together, allowing it to melt at a lower temperature.
Would new igneous rock be formed if Earths temperature did not increase with depth?
No, new igneous rock forms from the melting of pre-existing rock due to an increase in temperature with depth. If Earth's temperature did not increase with depth, there would not be enough heat to melt rocks and form new igneous rock.
Why might a very hot rock might not melt?
A very hot rock might not melt if it has a high melting point due to its mineral composition or if it has low heat conduction and is unable to reach its melting temperature despite being surrounded by heat. Additionally, pressure conditions can also affect the melting point of a rock.
If the temperature of rock rises above the melting point of the minerals the rock is composed of?
The rock will melt.
Does rock candy melt in room temperature?
No. If it did then it would melt in your hand. Rock candy is made mostly of sucrose, which does not melt but breaks down at 367 degrees Fahrenheit.
What temperature dose iron melt?
the iron melts at around 1535 degrease Celsius
What happens to rock when it is exposed to very high temperature?
Rock exposed to very high temperature and pressure will soften or melt.
Why metamorphic rock will form neither synthetically nor naturally if the temperature is too high?
If the temperature is too high, the rock will melt into magma and form igneous rock instead of metamorphic rock. Metamorphic rocks form under high pressure and temperature conditions, but if the temperature becomes too high, the rock will not be able to maintain its solid state and will melt.
How long does a a 1inch cube of ice take to melt with one spoon of mineral rock salt?
The time it takes for a 1-inch cube of ice to melt with one spoon of mineral rock salt can vary depending on factors such as the temperature of the environment and the specific properties of the salt. In general, adding salt to ice lowers its freezing point, causing it to melt faster. It typically takes a few minutes for the ice cube to fully melt with the addition of salt.
What occurs when the temperature on a rock is high enough to melt only some of the minerals in a rock?
they transform into magma
What three things control whether or not a rock will melt?
temperature, pressure, and fluid
If exposed to high enough temperature and pressures long buried igneous rock?
Melt and recrystallize
Why the Himalayas of India not melting?
Because the Himalayas are a mountain range, made of rock. The temperature is far too low to melt rock.
What type of rock does not melt?
Metamorphic rock is less likely to melt compared to igneous and sedimentary rocks due to its high temperature and pressure resistance. This resistance is due to the mineral composition and structure developed during the rock's formation.
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.
