There are three basic ways that rocks melt to form the lavas that erupt from volcanoes: decompression, addition of volatiles, and conduction.

Q. What happens when rocks cool quickly?
Any rock that forms from the cooling of magma is an igneous rock. Magma that cools quickly forms one kind of igneous rock, and magma that cools slowly forms another kind. When magma rises from deep within the earth and explodes out of a volcano, it is called lava, and it cools quickly on the surface.
Q. Why does temperature affect the crystal size seen in igneous rocks?
When magma cools, crystals form because the solution is super-saturated with respect to some minerals. If the magma cools quickly, the crystals do not have much time to form, so they are very small. If the magma cools slowly, then the crystals have enough time to grow and become large.
Q. What mineral has the highest melting point?
tungsten
Q. What rock has the highest melting point?
Melting Points of Rocks
| ApproximateTemperature (°C) | Minerals which are molten |
|---|---|
| 1200 | All molten |
| 1000 | Olivine, pyroxene, Ca-rich plagioclase |
| 800 | Amphibole, Ca/Na- plagioclase |
| 600 | Quartz, K-feldspar, Na-plagioclase, micas. |
Q. What is the most heat resistant metal in the world?
New record set for world’s most heat resistant material. Researchers have discovered that tantalum carbide and hafnium carbide materials can withstand scorching temperatures of nearly 4000 degrees Celsius.
Q. What metal can withstand 6000 degrees?
What material can withstand 6000 degrees? Tantalum carbide (TaC) and hafnium carbide (HfC) are refractory ceramics, meaning they are extraordinarily resistant to heat.
