large crystals (that form from volcanoes) form when lava under ground gets separated from the main lava chamber and begins slowly cooling. Smaller crystals form when either, one: Volcanoes erupt and lava cools, or two: Lava under ground gets separated from main lava chamber close to the surface and cools fairly quickly.

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
How ions are able to form large crystals?
by forming bonds
Why do crystals form on paper clips?
It is unusual for crystals to form on paper clips. Possibly if you use them to stir your coffee you might get sugar crystals.
Do ionic compounds form crystals?
Usually ionic compounds form crystals when in their solid state.
Why do different crystals have different colors?
Crystals form when they are in high pressure.
What are the conditions which small and large crystals are likely to form?
Large crystals form when a rock cools from magma slowly whereas smaller crystale form when there is a slow rate of cooling
When lava cools quickly large crystal form?
No. Small crystals form.
How do small crystals form?
Answer: Crystals usually form from molten rock as the molten rock gradually cools. If the molten rock cools very rapidly, then either small crystals form or no crystals form. An example of this is when lava is ejected from a volcano. If molten rock cools slowly, then large crystals can form. This happens usually when the molten material is very deep in the Earth. Examples of these types of crystals are diamonds, emeralds, rubies, etc.
How can small sugar crystals be used to form large sugar crystals?
Small crystals act as "seeds" and facilitate the formation of crystal growth, especially in super-saturated solutions.
If you wanted to create a rock that has large crystals in a laboratory what conditions?
The amount of time they have to form. the more time they have to form, the bigger they get.
Which Is what allows large crystals to form?
When magma coos slowly, it allows large crystals to form. The process of evaporation helps to form crystals.
Do igneous rocks have large crystals?
Yes, they can. Extrusive igneous rocks, which form outside the Earth's surface, often contain small or no crystals, because they cool quickly and the particles in the lava do not have much time to arrange themselves. Intrusive rocks, which form inside the Earth, generally have large crystals because they cool slowly. Granite is an example of an igneous rock with large crystals.
Where did an igneous rock form if the rock contains large crystals?
Usually from the slow cooling of magma with a plentiful supply of material necessary for crystal growth, and space in which to grow.
What causes minerals to form large and small crystals within the same rock?
Recrystallization. Recrystallization is a process whereby small crystals of one mineral will slowly convert to fewer, larger crystals of the same mineral, without melting of the rock.
What affects the size of crystals formed from magma?
The rate at which the magma cools affects the size of the crystals that form. If it cools slowly, large crystals will form. If it cools rapidly, small crystals will form.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
Do large well -formed crystals cool quickly?
Large, well formed crystals form in solutions that cool rapidly. When solutions cool slowly, crystals are more likely to nucleate in higher numbers at the same time, leading to many very small and irregular shaped crystals.
How does the cooling rte of rocks affect the crystal size?
If rock cools quickly it does not have time to form large crystals and so it forms small ones. At slower cooling rates there is time to form larger crystals.
