Melting water can weather a rock through a process called frost wedging, where water seeps into cracks in the rock, freezes and expands, causing the crack to widen. This cycle of freezing and thawing can break apart rocks over time. Additionally, the flowing water can chemically weather the rock by dissolving minerals and carrying them away.

How does the presence of water affect the melting temperature of a rock?
The presence of water can lower the melting temperature of a rock by facilitating the movement of ions and promoting the process of melting. Water reduces the viscosity of molten rock, making it easier for the rock to melt at lower temperatures.
What happens when water is added to rock in the mantle?
When water is added to rock in the mantle, a process called hydration occurs where the water reacts with the minerals in the rock to form new minerals. This can lead to changes in the rock's composition, structure, and physical properties. Additionally, the presence of water can lower the melting point of the rock, potentially leading to the formation of magma through partial melting.
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.
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.
The melting of metamorphic or igneous rock forms what substance?
The melting of metamorphic or igneous rock forms magma, which can eventually cool and solidify to form igneous rock.
How does water affect the melting temperature of rock at a convergent boundry?
Water reduces the melting point of rock.
Does rock candy melt in water?
No. Rock candy dissolves in water, which is different from melting.

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.)

What allows rock melting to begin at convertgent plate boundaries?
Water reducing the melting point.

A wet rock generally melts at a lower temperature than a dry rock true or false?
True. Water has a lower melting point than most rocks, so when a rock is wet, the presence of water can lower the overall melting point of the rock.
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.
Is water a contributer to a rock's melting temperature?
Yes, water can lower the melting temperature of rocks by promoting the melting process through a mechanism called flux melting. This occurs when water is incorporated into the rock, causing it to melt at lower temperatures than it would under dry conditions.
In the rock cycle water and weather wear away rock by the process of?
Weathering.
What body of water can cause a rock to weather?
he constant movement of water anywhere causes rocks to erode and weather.
