What determines the mineral grain size in an igneous rock?
The cooling rate of the rock.
What can determine the size of grains in igneous rocks?
Cooling rate of molten rock
What determines the size of crystals that form in granite?
The cooling rate of magma plays a significant role in determining the size of crystals.
Is it true as magma cools it's atoms tend to move away from each other?
The slower the rate of cooling the larger the size of the crystals that can develop.
What factors causes the difference in the size of crystals formed?
factors include: saturation, rate of cooling, temperature, and the crystal itself...
How is the size of the mineral grains affect by the rate at which molten rock material rock?
The slower the rate of cooling the larger the size of the crystals that can develop.
What determines the mineral grain size in an igneous rock?
The cooling rate of the rock.
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.
Size of sedimentary mineral crystal grain?
that means like when somthing is in a own properties
How does the rate of cooling affect the size of copper sulphate Chrystals?
larger crystals
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
As the rate of cooling increase the size of the crystals that form?
The size of the crystals that do form are smaller/microscopic in that the time an temperature for crystals to grow is cut. The type of mineral that crystallizes is also effected,
Variables that affect the rate of weathering?
Exposure, Particle size, mineral composition, & climate.
What is the affect of temperature on crystal growth?
Temperature doesn't really affect the crystal size; the rate of cooling is the major factor. The faster the mineral, rock, etc. (whatever has the crystals) cools, the smaller the crystals- the slower the larger. If you were "growing" crystals with a set, the warmer the temperature generally means the larger the crystals.
What determines the size of a mineral crystal formed from magma?
The rate at which magma cools determines the size of the mineral crystal.
How grain size depends on the rate of cooling?
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
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.
