Does melted rock that cools quickly result in igneous rock with large mineral crystals?
No, melted rock that cools quickly result in igneous rock with large minerals because large crystals take time to form and the rocks that usually have them are the ones that were formed inside the earth.
Do igneous rocks have large crystals?
Yes, they can. Extrusive igneous rocks, which form outside the Earth's surface, often contain small or no crystals, because they cool quickly and the particles in the lava do not have much time to arrange themselves. Intrusive rocks, which form inside the Earth, generally have large crystals because they cool slowly. Granite is an example of an igneous rock with large crystals.
What type rock forms when magma cools and hardens?
Igneous Rock is formed when magma cools and hardens. It depends on whether it cools above ground or under ground for the size of the mineral crystals forming inside it.
Why do some igneous rocks have large crystals while others have small crystals or no crystals?
Mostly, it depends on cooling time. If a rock cools very rapidly, a smooth texture is formed as the atoms quickly arrange themselves into a fairly smooth crystalline pattern. Think of obsidian; it cools very fast and has such small crystals looks like black warped glass. However, if a rock was formed below the Earth's surface (intrusively) like in a pluton, it will cool more slowly and will be rougher and have larger crystals.
Melted rock that flows to the surface cools quickly forms?
Igneous rocks are formed when molten hot rock flows to the surface of the Earth and rapidly cools down. The crystals that form are rich in silicon and oxygen.
If lava cools to quickly that ions don't have time to arrange themselves into crystals will form what?
glassy texture, hope this helps :)

What size are the crystals in an igneous rock that cools quickly?
Small
If the lava cools quickly the crystal are what?
If lava cools quickly, the minerals don't have as much time to form crystals, so the crystals do not become very large. Igneous rocks that cooled quickly and have small crystals are described as "aphanitic" igneous rocks.
What type of crystals will igneous rock have if it cools quickly?
Small ones.
What rock cools on the surface?
Lava cools quickly and forms rocks with small crystals. They are called extrusive igneous rocks.
Why Is the crystal in igneous rock small if it cools quickly from magma?
The crystals within don't have as much time to grow when igneous rock is cooled more quickly as in extrusive igneous formation.

Magma cools slowly atoms cant arrange into crystals?
IF the magma cools slowly witin Earths eated interior the atoms have time 2 arrange themselves into large crystals!
what is a type of igneous rock that cools quicklymmmmmm?
Well when an igneous rock cools quickly, it ends up being fine-grained, as there wasn't any time for large crystals to form. Examples include andesite, basalt, tuff, scoria, etc. Obsidian is also the result of lava cooling extremely quickly, to the point where no crystals whatsoever were able to form.
What type rock forms when magma cools and hardens?
Igneous Rock is formed when magma cools and hardens. It depends on whether it cools above ground or under ground for the size of the mineral crystals forming inside it.
