Grain size depends upon the cooling rate as written below:
1.
longer the time it takes to cool,
larger will be the grain size
and vice versa

What controls the grain size of igneous rock?
The rate at which the igneous rock cools controls grain size. Slower cooling results in larger crystals while faster cooling results in smaller crystals.
What effect does a fast cooling rate have on grain size in igenous rocks?
Fast cooling lava or magma creates an aphanitic or small crystal (grain) textured igneous rock.
Size of sedimentary mineral crystal grain?
that means like when somthing is in a own properties
. As the rate of cooling of igneous rocks increases the size of the crystals that form?
The size of crystals decreases as the cooling increases. This is called an inverse relationship.
As the rate of cooling of igneous rocks increases the size of the crystals that form?
The size of crystals decreases as the cooling increases. This is called an inverse relationship.
What determines the mineral grain size in an igneous rock?
The cooling rate of the rock.

What is a factor that controls grain size in igneos rocks?
Crystal size in igneous rocks is controlled by the rate of cooling whereby the slower the rate, the larger the size of crystal.

What are three things crystal size dependent on?
Primarily the cooling rate of the mineral compound.The faster the rate cooling smaller the crystal size of the mineral.Consequently, large crystal specimins are derived from igneous bodies with a very slow rate of cooling.
What effect does heating and cooling have on metallic structures (more specifically grain size)?
The dimensions grains in metals are modified by heating or cooling.
As the rate of cooling of igneous rocks increases the size of the crystals that form?
The size of crystals decreases as the cooling increases. This is called an inverse relationship.
As the rate of cooling of igneous rocks increases the size of the crystals that form .?

What factors can effect the texture of a igneous rock?
The texture is determined by the rate it takes the molten to cool to form the rock.
How does the speed of cooling of molten rock affect the size of crystals that form?
fast cooling rate forms smaller crystals eg Andesiteslow cooling rate forms large crystals eg.Pegmatite
