How does freezing and melting water weather rocks?
Water erodes rocks by taking away little bits, and water gets into the little pits of a rock, and when it freezes, the water expands and makes the pits/cracks bigger. Over time, this breaks the rocks down.
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 the presence of water affect the melting temperature of a 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.
What causes melting of material under divergent plate boundaries Is it melting of rock recompression of rock freezing of rock or decompression of rock?
decompression of rock
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.
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.

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.
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.
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.
How are rocks weatherd?
When rocks are broken down without any change to their chemical compositions it is mechanical weathering. Causes of mechanical weathering are Freezing and melting of water, Abrasion, when the rock is weather by an abrasive agent such as wind and sand, and exfoliation occurs when a rock is brought to the surface.
