It depends on the cooling of lava. Slow cooling forms big crystals deep under the surface while fast cooling creates small crystals on or just below the earths surface. Itstant cooling wouls have no crystals.

∙ 11y agoThe thing that affects the igneous rocks crystals is the speed the magma cools at, the longer it takes to cool the bigger the crystals, intrusive means big crystals and extrusive means small crystals just for note.

What do extrusive igneous rocks look like?
The particle size (grain size--crystal size) in igneous rock is largely dependent on the amount of time spent cooling and solidifying from molten rock. If cooled quickly, crystals will have little time to grow. Slow cooling allows time for larger crystal growth.
What is the best evidence for determining the cooling rate of an igneous rock during its solidification is provided by what?
the crystal size of its minerals

What determines the size of the crystals that form in a sample of granite?
Crystal size in igneous rock is predominately a factor of time spent in cooling from lava or magma. Samples with relatively large crystals are the result of the magma having spent a longer amount of time at ideal crystal forming temperatures for each mineral present.
What determines the size of a mineral crystal formed from magma?
The rate at which magma cools determines the size of the mineral crystal.
Does igneous rock texture refers to size?
please anyone else can answer this question I'm in hurry pls.
What size of rock texture refers to igneous rock?
The size of the mineral crystals in an igneous rock determines the rock's texture.
What is The crystal size of an igneous rock is described as?
texture
The crystal the size of an igneous rock is described as its what?
texture
What determines the mineral grain size in an igneous rock?
The cooling rate of the rock.
Which crystal can help identify as igneous rock as intrusive or extrusive?
What is the effect of location on crystal size? Label the location of intrusive and extrusive igneous rocks on the diagram below. Then, illustrate the crystal size of the rock formed at that location in the appropriate callout circles.
What size is an intrusive Igneous Rock?
It can be any size. The only specific factor of the intrusive rock is that is took a very long time to cool.
What determines the size of grains in igneous rocks?
The cooling rate of molten rock
