Why are felsic rocks melted by mafic magmas but mafic rocks are not melted by felsic magmas?
Felsic rocks have a lower melting point than mafic rocks and felsic magma has a lower temperature. In other words, felsic magma is not hot enough to melt mafic rock while mafic magma is hot enough to melt felsic rock.
How does the composition of magma affect the temperature at which it solidifies?
Magma consists of molten rocks and metals. The composition can vary based on presence of water, metals with different melting points, and such.
How does melting point change as the water content of rocks increases?
The presence of the water in its vapor phase causes the melting point to decrease and the rock to melt and absorb the vapor.
How does the coposition of the magma affect the temperature at which it solidifies?
The composition of the magma is very important for solidificatoin temperature. When it starts to cool, crystals of minerals begin to grow. If it has a low silica content - which means high melting point - the magma will solidify at high temeratures. If it has a high silica content - which means low melting point - it will solidify at lower temperatures.
Is the melting point of organic compound high or low?
Melting point is important in organic chemistry because it can be used for the identification of a compound. For pure solid organic compounds will have a small melting point range (0.5-10C),thus presence of impurity can also be find out by Melting point.
Why are felsic rocks melted by mafic magmas but mafic rocks are not melted by felsic magmas?
Felsic rocks have a lower melting point than mafic rocks and felsic magma has a lower temperature. In other words, felsic magma is not hot enough to melt mafic rock while mafic magma is hot enough to melt felsic rock.
Can magma met a diamond?
The melting point of diamond is sufficiently high that magma would not melt it.
When magma forms within the mantle it is most often a result of?
Either the loss of confining pressure causing the melting point of the material to drop below the in-situ temperature or due to the presence of volatiles which enter the mantle where subduction occurs and also lower the melting point of the material.
Under what conditions does magma form?
Magma forms where rock is heated to a temperature above its eutectic melting point.
Will magma melt diamond?
a diamond's melting point is so highmagma will not melt it
What is melting point of acetamide?
The melting point is influenced by the presence of impurities in the material.
How does the composition of magma affect the temperature at which it solidifies?
Magma consists of molten rocks and metals. The composition can vary based on presence of water, metals with different melting points, and such.
What happens when temperatures of rock rises above its melting point?
The rock melts to form magma.
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. :)
How does melting point change as the water content of rocks increases?
The presence of the water in its vapor phase causes the melting point to decrease and the rock to melt and absorb the vapor.
How is phenylthiourea prepared and what is its melting point?
heating benzoylthiourea in the presence of base such as sodium hydroxide
