What happens when the temperature of rock rises above its melting point?
When the temperature of a rock rises above its melting point it turns into magma, usually found in the mantle (found below the Earth's crust).
What is incipient melting point?
The incipient melting point refers to how metal is heated. It is the point just before the metal reaches its melting point.
Do solids have a high or low melting point?
That depends on the solid: ice has a very low melting point, lard and butter have low melting points, chocolate has a relatively low melting point, wax has an intermediate melting point, lead has a high melting point, iron has a very high melting point, tungsten has an extremely high melting point.
What is the melting point of gold silver and copper?
Melting point of Gold = 1064.18 °C Melting point of Silver = 961.78 °C Melting point of Copper = 1084.62 °C Of cause an alloy of all three would probably have a eutectic melting behavour
What is the melting point of ice on the top of Himalayan?
what is the melting point of ice on top of the Himalayan
Does the presence of water raise the melting point of felsic magma?
No. Water lowers the melting point of magma, both mafic and felsic.
Can magma met a diamond?
The melting point of diamond is sufficiently high that magma would not melt it.
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 happens when temperatures of rock rises above its melting point?
The rock melts to form magma.
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.
What has an area of rock that flows like thick liquid?
A volcano; magma is merely rock that has been heated to the point of melting.
What process causes the melting of the asthenosphere and the generation of magma?
The melting of the asthenosphere and the generation of magma primarily occur through a process called decompression melting. As tectonic plates move apart at mid-ocean ridges or hotspots, the reduction in pressure allows the mantle material to melt, forming magma. Additionally, the introduction of volatiles like water lowers the melting point of mantle rocks, facilitating further magma generation. This process is crucial for volcanic activity and the formation of new crust.
How does magma occur?
Magma occurrs by rocks melting inside a volcano
Where do you get your magma from?
Magma comes from the melting of material in the crust or upper mantle.
Will rhyolitic magmas erupt at lower temperatures than basaltic magmas?
Yes, rhyolitic magmas are several hundred °C colder than basaltic magmas. This is because the melting point of a rhyolitic magma is much lower than that of basaltic magma. Instead of heating up rhyolitic magma much above its melting point it will ascend and either crystallize in the Earth's interior as a pluton or erupt.
What happens when the temperature of rock rises above its melting point?
When the temperature of a rock rises above its melting point it turns into magma, usually found in the mantle (found below the Earth's crust).
