What conditions lead to the formation of large crystals in an igneous rock?
Igneous rocks will develop large crystals is they cool slowly underground.
Do intrusive rocks have large crystals because they cool quickly?
No. Intrusive igneous rocks have large crystals because they cool slowly.
Are igneous rocks formed from smalll minerals?
Not necessarily. Intrusive igneous rocks, especially pegmatites, can have large crystals.
What is the texture of igneous rocks with large crystals that slow cooling produces?
Phaneritic.
What are large mineral crystals commonly found in?
large mineral crystals are most likely found or have grown in igneous or metamorphic rocks
Do igneous rocks have small crystals large crystals or no crystals?
It depends on the type of igneous rock. Intrusive igneous rocks such as granite have large crystals, extrusive igneous rocks may have small crystals as in basalt or no crystals as in pumice.
What are Igneous rocks that have large crystals and small crystals?
Such rocks are called porphyritic.

Not necessarily. Intrusive igneous rocks, especially pegmatites, can have large crystals.
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.
Rocks that have crystals?
Igneous rocks
What is the texture of igneous rocks with large crystals that slow cooling produces?
Phaneritic.
What do the large crystals in igneous rocks tell about the rock?
That it cooled very slowly.
Intrusive Igneous rocks are characterized by a coarse-grained texture because they contain?
Intrusive igneous rocks commonly have large mineral crystals.
