Why would you expect a metamorphic rock to form at a temperature lower then the melting point of rock?

If the rock melts the resulting rock type would be igneous rather than metamorphic.

Is the earth's crust melting point lower than it's actual temperature?
No. If the melting point was higher than its actual temperature then the crust would be molten.
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.
Why caesium is liquid at nearly room temperature?
Why not? Or, in other words, there's not really a "why" to explain here; it's an extension of a well-established trend (unlike mercury, which is a liquid at room temperature while all the metals around it are solid and there's no such trend that would predict its dramatically lower melting point). The trend for alkali metals is that they have lower melting points as you move down the table. By the time you get to caesium, it's only a little above room temperature, and the theoretical melting point for francium is even lower than that (but still slightly above room temperature).
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 to the melting point temperature as pressure increases?
Corrected:In water, there is a small DEcrease in melting temperature of ice, as pressure increases.Added:In 'Related links' attached to this page (lower left corner) a diagram-picture of"Melting point: Temperature and Pressure" is shown asGreen line for most 'normal' solidsand ofWater-Ice: it is the Green-Dotted line.
Why would you expect a metamorphic form at a temperature lower than the melting point of a rock?
if rock melts it will form magma, which leads to the formation of igneous rocks
Why would you expect a metamorphic rock to form at a temperature lower than a melting point rock?
Metamorphic rocks form by rocks being changed while still in the solid state. If the temperature of a rock exceeds its melting point, it will melt and any rock that forms as a result will be considered igneous.
Is The melting temperature of an alloy is generally lower than its constiuants?
The melting temperature of an alloy is generally lower than the melting temperature of the highest melting temperature of all of its constituents. The eutectic melting temperature is the lowest melting temperature of an alloy system and is in fact sort of defined by that optimal set of percentages of those constituents. The next obvious question is whether there are calculation methods or approximations to determine the melting range of less than "eutectic" percentages.
The temperature at which a substance freezes is lower than the temperature at which it melts?
Correct, the temperature at which a substance freezes is lower than the melting point.
What state is it if the temperature is lower than melting?
Solid state
Is the temperature of the outer core higher or lower then the melting point?
higher
What is lower fixed point?
upper fixed point is a temperature of stem from water boiling and standards atmospheric pressure lower fixed point is the temperature of pure melting ice.
Is the earth's crust melting point lower than it's actual temperature?
No. If the melting point was higher than its actual temperature then the crust would be molten.
Is the temperature of the inner core higher or lower than its melting pointing?
higher
Is the temperature of the inner core higher or lower than its melting point?
higher
Which is true of a melting point and a boiling point?
Melting point: at this temperature a solid become a liquid.Boiling point: at this temperature a liquid become a gas.
Why do covalent bonds generally have lower melting temperatures but are stronger than ionic bonds?
because they are lower in temperature
