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.
When rocks return to the earths mantle they can eventually melt and become magma what are the main factors that control this change?
The main factors that control the melting of rocks and their transformation into magma in the Earth's mantle include temperature, pressure, and the presence of fluids. As rocks descend into the mantle, increasing temperatures can cause them to reach their melting points. Additionally, higher pressures can raise the melting point of rocks, while the introduction of water and other volatiles can lower the melting point, facilitating the melting process. These factors work together to influence the formation of magma from solid rocks in the mantle.
Can metamorphic rocks be created by melting?
Nope, because they are created when the Earth pressurizes and heats it (but not to the point of melting). Igneous rocks are created when rocks melt.
Can heat cause some rocks to melt and change into new rocks?
Yes, heat can cause rocks to melt and form new rocks through the process of melting, cooling, and solidifying. This can lead to the formation of igneous rocks from both existing rocks and molten rock material.
What rocks result from heat and pressure melting into magma?
sedimentary rocks
How do rocks change from metamorphic or sedimentary rocks to igneous rocks?
Metamorphic and sedimentary rocks can change into igneous rocks through the process of melting and cooling. When subjected to intense heat and pressure, the rocks can melt and form magma. This magma can then cool and solidify, forming igneous rocks.
What pr ocesses change sedimentary rocks into metamorphic rocks?
heat and pressure, but without melting.
Does rock have to melt in order to change form?
No, rocks can change forms through processes like erosion, pressure, and heat without completely melting. Rocks can metamorphose through heat and pressure to form new types of rocks without fully melting.
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.
In terms of rock cycle why do minerals and rocks change over time?
They change because of exposure to weathering, erosion, heat, pressure, and melting.

How does matter in rocks change to matter in water?
Water can dissolve some of the matter found in rocks. Also, through the alternating processes of freezing and melting, water can cause pieces of rocks to fall into it.
Can heat cause some rocks to melt and change into new rocks?
Yes, heat can cause rocks to melt and form new rocks through the process of melting, cooling, and solidifying. This can lead to the formation of igneous rocks from both existing rocks and molten rock material.
What rock changes?
Everything. There is so many ways to change rocks. Erosion by Wind and Water. Earthquakes/Plate Tectonics, Subduction leading to metamorphism and ultimately melting and becoming Igneous. Man.
How do igneous rocks change into 'sedimentary rocks?
AnswerUsually by subduction of sedimentary rock at plate boundaries, melting, and deposition as solidified crustal igneous rock, either extrusive or intrusive.
What rocks result from heat and pressure melting into magma?
sedimentary rocks
