What factor determine the size of crystals in metamorphic rocks?
Large mineral crystals that are all about the same size are formed from magma that cooled slowly inside the earth. Small mineral crystals (not identifiable without a microscope) formed from magma that cooled rapidly, on or near the surface of the earth.
In what two ways can the parent rock affect the metamorphic process?
One of the two ways that parent rock affect the metamorphic process is through the mineral makeup. Another factor is chemical composition.
What factor most influences the size of mineral crystals in igneous rocks?
The major factor is the amount of time the magma remains mostly liquid while cooling and solidifying. More time spent cooling produces larger crystals because of the free movement of a mineral's constituent isotopes in a somewhat liquid magma.
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.
How can you tell the difference between an igneous rock that formed above ground and one that formed below?
Usually, the determining factor is the size of the mineral crystals in the rock. Igneous rocks that have solidified above ground cool quickly and have less time for larger crystals to grow.

Which is a factor that affects the size of a mineral crystals formed in magma?
evaporation
Which is a factor that effects the size of mineral crystals formed in magma?
fluoresence is not a factor. I had this same question and i got fluorescence as a correct answer

What is factor that affects the size of mineral crystal formed in magma?
The main factor is time spent in cooling and solidifying. More time means larger crystals.

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.

Can color be a definitive factor in determining a mineral?
can color be a denitive factor in determinig a mineral

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.
