if it takes the rock a long time to cool down the crystals will be bigger if the rock takes a short time to cool the crystals will be smaller

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.
What feature in igneous rocks is the best indication of how rapidly the magma crystallized?
The size of the crystals. Large crystals mean the magma cooled slowly, small crystals are a sign that the magma was cooled quickly.
What is the relationship between cooling time igneous rocks and the size of its crystals?
Plutonic rocks are intrusive (they solidify before they reach the surface) and have larger crystals because the crystals have had a longer time to accumulate in the heat under the surface. Volcanic rocks are extrusive (they solidify on or near the surface) and have smaller crystals because the element has less time to accumulate when they cool quickly.
Why is it that some igneous rock is made of large crystals and some is made of small crystals?
An igneous rock's crystal size is dependent on how long it takes to cool from magma into a solid. Intrusive igneous rocks, the ones that solidify from magma underground, are slow to harden, giving crystals plenty of time to grow larger. Extrusive igneous rocks, formed from lava above ground, cool fairly rapidly, not allowing the crystals much time to grow in size.
What determines the size of a mineral crystal formed from magma?
The rate at which magma cools determines the size of the mineral crystal.
What affects the size of crystals formed in magma?
balloon
Is a factor that affects the size of minerals crystals formed in magma?
evaporation
Which is a factor that affects the size of a mineral crystals formed in magma?
evaporation
What affects th size of crystals formed from magma?
the slower the magma cools the bigger the crystal is
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 factor affects the size of the crystals in minerals that form from magma or lava?
If the lava cools quickly the crystals will be smaller than if it cooled slowly.

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 type of crystals is formed from slow cooling?
If the magma cools down fastly the crystal size is small because the crystals do not have much time to form. If They magma slows down slowly the crystal size is big because it gives the crystals time to form! :D
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 the main factor that affects the size of minerals in igneous rocks?
Crystal size is largely dependent on the time the magma takes to cool and solidify. Slow cooling equals large crystals. Fast cooling equals small crystals.
