Magma cools down about a week or so it is extremely hot about 350 degrees Fahrenheit , when it cools down it turns into crystals which are inorganic, naturally, solid, and having a atom arrangement.

∙ 12y ago1 sorry for sounding mean but just mentioning all magma is beneath the surface. It cools very slowly, because the is great heat under the surface that is barely lower then the magma itself. A way to know if a mineral is magma that cooled under the surface if it crystallizes. If it cools slowly then and only then is there time for crystallization. For instance obsidian which is magma that cooled in the ocean doesn't have crystals because it cooled too quickly for crystals to form.

Does intrusive rock cool fast or slow from magma?
slow
Do intrusive igneous rocks form quickly or slowly?
Fast and slow are relative terms. If a heated igneous rock takes 3 hours to cool, is that fast or slow? During their formation, however, magma can solidify very slowly or very quickly. Rocks that have cooled quickly from magma are referred to as extrusive igneous rocks, such as obsidian and scoria. Rocks that have formed from slow cooling magma are called intrusive igneous rocks, such as granite and gabbro. The difference between the two types is in their grain size. Slow cooling magma produces large grained rock, and fast cooling magma produces fine-grained rock.
Why does basalt cool fast?
Basalt cools fast because it is at the surface, where air carries heat away rather quickly.
Is basalt cooled slowly?
In reference to the cooling of magma into rock, basalt is formed from rapid cooling.
What size crystal do magma make?
it depends on if it is intrusive or extrusive (intrusive is below the earth and extrusive is at or above the earth) intrusive has a bigger crystal because it takes time to cool down.
How does the shape surface area and volume affect how fast magma cools?
The shape affects the ratio of surface area to volume. The greater the surface are to volume ratio, the faster the magma will cool.
What is the origin of obsiadan?
If you are asking about how they were formed magma from volcano that are shot in the air of quickly spewed out causing the magma to cool very quickly forming a very smooth surface on obsidian. Becuase the magma cooled so fast it couldn't slowly cool into a rough textured rock.
Hot fast moving lava?
The center of the earth is the hottest, and the crust is the furthest away from that heat.

What is the difference between intrusive and igneous rocks?
The difference between an Extrusive and Intrusive igneous rock is the way in which they cool. An Extrusive igneous rock cools very fast on the surface and is created by lava. Since the cooling process is very fast extrusive igneous rocks have very small crystals (fine grained). On the other hand an Intrusive igneous rock cools very slowly beneath the surface and is created by magma. Since the cooling process is very slow intrusive igneous rocks have very large crystals (coarse grained). In some instances there is also a third type of igneous rock. Technically it is an extrusive rock, but it resembles glass. This glass type of igneous rock forms when magma/lava is instantly cooled.

Does andesite cool quickly or slowly?
Lava will cool quickly compared to underground magma.
How fast does the magma from an erupted volcano go?
it go pretty fast
Why does rhyolite cool fast?
Rhyolite cools fast because it forms at the surface. Air carries heat away from molten rock much faster than the rock deep underground.
