How is the size of crystals in an igneous rock related to the formation of a rock?
If an igneous rock is formed from slowly cooling magma under the ground, it has more time to form crystals and so the crystals it forms are much larger than igneous rock formed from more quickly cooling magma or lava.
What factor determines if an igneous rock has no crystals small crystals or large crystals?
it depends on the heat, if it cool very quick then it has small crystals but if it cool very slowly than it is bigger the slower the cooling period the bigger the crystals
What type of rock that forms from magma or lava is rock?
Igneous rock is formed from the cooling of magma or lava.
What conditions lead to the formation of large crystals in an igneous rock?
Igneous rocks will develop large crystals is they cool slowly underground.
Why do some igneous rocks have larger crystals than others?
The size of the crystals depend on the time it took the rock to cool. Slow cooling rocks have larger crystals because they had a longer time to grow their crystals. For example Basalt is an volcanic extrusive igneous rock that forms from rapid cooling of the magma and are usually located near the surface or on the ocean floor, it has finer crystals not visible by the naked eye. Granite is an intrusive igneous rock that forms from slow cooling of the magma within the earth crust, it has larger crystals.

How is the size of mineral crystals in igneous rock related to the rate at which they cool?
When igneous rocks cool quickly, they have small crystals and have a texture that may be described as aphanitic. When igneous rocks cool slowly, they have much larger crystals and have a texture that may be described as phaneritic or pegmatitic.
Is the crystal in the igneous rock large if it cools slowly from magma?
Yes. Slow cooling magma produces larger mineral crystals.
What factor determines if an igneous rock has no crystals small crystals or large crystals?
it depends on the heat, if it cool very quick then it has small crystals but if it cool very slowly than it is bigger the slower the cooling period the bigger the crystals
What kind of igneous rock texture results from slow cooling magma?
A coarse grained texture, referred to as a phaneritic texture, will be the resultant igneous rock texture. The slower the magma cools the more time minerals have to crystallize and thus grow bigger.
Is granite igneous or metamorphic?
igneous. Made from slowly cooling magma. :)
What condition lead of the formation of large crystals in an igneous?
Igneous rocks will develop large crystals is they cool slowly underground.
How does the crystal sizes of igneous rocks indicate the rate of cooling and whether the rock is extrusive or intrusive?
Generally, large crystals represent slow cooling rates and small crystals represent fast cooling rates. Crystals need time to form and since extrusive rocks cool very quickly, they have very tiny crystals and some don't even have crystals because the rate of cooling was so fast that crystals didn't have time to nucleate. On the other hand, intrusive rocks cool rather slowly allowing crystals to grow.

What type of crystals form when magma cools very slowly deep beneath the Earth's surface?
Large crystals are formed in igneous rock that forms from slow cooling magma, deep beneath the Earth's surface.
