What affect does the presence of water have on the melting temperature of a rock?
The presence of water can lower the melting temperature of a rock by facilitating the transfer of heat and promoting the formation of liquid magma. Water can act as a flux, which helps to break chemical bonds in the rock and decrease its melting point. This process is commonly seen in the formation of magmas in subduction zones and other tectonically active regions.
How does water affect the melting temperature of a mineral?
Water can lower the melting temperature of a mineral by acting as a flux or catalyzing agent, allowing atoms to move more freely and reducing the energy required for melting. This can lead to the formation of new minerals or phases at lower temperatures than would occur without water present.
What are the factors that affect the formation of magma?
1. a decrease in pressure, which lowers the melting temperatures of materials; this occur at mid-ocean ridges. 2. an increase in pressure, which causes materials in the asthenosphere to melt; this often occurs at a hot spot. 3. an increase in the amount of water in the asthenosphere, which lowers the melting temperatures of materials; this often occurs at subduction boundaries.
How does icebergs affect the water?
well the temperature of the earth is rising, and since icebergs are pretty much big chucks of frozen water, when they melt were stuffed 'cause it'll end up with probably half the earth underwater
Can A wet rock generally melts at a lower temperature than a dry rock?
Yes, a wet rock generally melts at a lower temperature than a dry rock because the presence of water decreases the melting point of the rock. Water acts as a solvent, facilitating the movement of ions and reducing the energy required for melting to occur.
How does the presence of water affect the melting temperature of rock?
The presence of water lowers the solidus temperature of rocks at a given pressure. It drastically changes the melting temperature by a vast amount.
How does water affect the melting temperature of rock at a convergent boundry?
Water reduces the melting point of rock.

How does the composition of the magma affect the temperature 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 water temperature affect the melting rate of ice?
the hotter the water the faster the ice will melt
Is water a contributer to a rock's melting temperature?
Yes. The presence of water can significantly reduce the melting temperature of rock. For example the presence of water and other volatiles in a subducting slab of oceanic crust that acts to significantly reduce the melting temperature of the mantle material above it leading to the formation of magma and the volcanism that is associated with subduction zones.
What factors affect the melting and freezing points of water?
The melting and freezing points of water are primarily affected by external pressure and the presence of impurities. Increasing pressure raises both points, while adding impurities lowers them. Additionally, the purity of the water molecules and the surrounding environment's temperature also play a role.
How does melting point change as the water content of rocks increases?
As the water content of rocks increases, the melting point typically decreases. This is because the presence of water lowers the melting point of minerals in the rocks by acting as a flux that promotes melting. The addition of water creates a eutectic point where the rock will begin to melt at a lower temperature.
How does water affect melting temperature of rock at a convergent boundary?
It doesn't. It does slow the melting of rock, but only because of the specific heat of water. (i.e. you've got to heat the water too.)
How does water affect the melting temperature of rock at a convergent boundary?
It doesn't. It does slow the melting of rock, but only because of the specific heat of water. (i.e. you've got to heat the water too.)
How does adding salt to melting ice affect the rate of melting?
Adding salt to melting ice lowers the freezing point of water, causing the ice to melt at a lower temperature. This results in faster melting of the ice.
How does water affect the melting temperature of a mineral?
Water can lower the melting temperature of a mineral by acting as a flux or catalyzing agent, allowing atoms to move more freely and reducing the energy required for melting. This can lead to the formation of new minerals or phases at lower temperatures than would occur without water present.
