What happens to the melting point of plagioclase feldspar when it is pushed further into the earth?

the melting point decreases as pressure increases, so the further into the earth feldspar is pushed, the higher the pressure and the lover the melting point

Why Does Chlorine or Silicon have a higher melting point?
the further one moves down the periods, the melting point decreases. since sillicon is placed before chlorine, chlorine has lower melting point.
What happens when water is added to rock in the mantle?
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.
Rocks melt at what temperature range?
Felsic rocks have the lowest melting point, ranging from 600 to 750 degree Celsius. Felsic rocks are light colored and their melts don't consist of enough magnesium, iron and calcium to produce pyroxene, olivine or calcium plagioclase.
What is the state of sulfur at 20 degrees Celsius?
Sulfur is a solid. Its melting point is 115.21 0C, See related link for further information.
What do you call the temperature at which a solid changes to a liquid?
This is the melting point.
What is the first minerals tends to form by Bowen's Series?
Bowens' Reaction Series measures the melting points of various silicate minerals, with the ones with highest melting points at the top. So as a completely moltenmagma containing all these minerals cools down, the first to crystallise are:ABOUT 1400 CELSIUSOlivinePyroxene (e.g. augite)Amphibole (e.g. hornblende)Biotite micaOrthoclase feldsparMuscovite micaSilica (e.g. quartz).ABOUT 800 CELSIUSNotice I've deliberately left out plagioclase feldspar because plagioclases of different composition crystallise out at different temperatures. Calcium-rich plagioclase crystallises out at about the same temperature as olivine (mineral 1), but sodium-rich plagioclase crystallises out about the same temperature as biotite mica (mineral 4). All plagioclase crystallises out at a higher temperature than orthoclase (mineral 5).So in answer to your question the first minerals to form as a magma cools are olivine and calcium-rich plagioclase feldspar, at around 1400 Celsius.
Would quartz or plagioclase be more likely to form a well shaped crystal in an igneous rock?
A well-shaped crystal in an igneous rock needs room and time to grow. So, minerals with high melting points form well shaped crystals while ones with lower melting points don't because there isn't as much time for them to form. Quartz crystallizes at a lower temperature than plagioclase so plagioclase is more likely to form well-shaped crystals.
A mineral commonly used for melting ice on slippery winter surfaces is?
halite (salt)
Why does the temperature become constant at the point of melting till the whole substance of a solid melted?
That happens because any heat that is added to that melting material will be used to cause further melting, until there is nothing left to melt, at which point the added heat can raise the temperature. A solid melts at its melting point; it does not get hotter than the melting point without melting, that's why it is the melting point.
What happens when the temperature stays the same in a melting curve?
During melting the temperature remain constant if it was achieved the melting point.
What happens in the melting point of ice?
it evaporates

its chngein 2 a liquid
What happens at the melting point of an object?
Depends on what the object is.
What happens if you melt a lighter?
it will explode if your melting it on a fire
