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.

How ions are able to form large crystals?
Ions are able to form large crystals through a process called crystallization, where they come together in an ordered arrangement to minimize energy. This occurs when the ions are in a solution and conditions like temperature and concentration allow for the ions to align and grow into a well-structured crystal lattice. Over time, more ions join the crystal lattice, leading to the formation of large crystals.
What type of crystals is formed from slow cooling?
Crystals formed from slow cooling typically have larger crystal sizes due to more time for the atoms to arrange in an ordered structure. This results in minerals with well-defined crystal faces and clearer textures, as seen in intrusive igneous rocks like granite and gabbro.
A mineral specimen has very large crystals what is the best explanation for how this happend?
Large crystals in a mineral specimen typically form when the mineral has enough time and space to grow without being obstructed by nearby crystals. This often occurs in environments with slow cooling rates or low levels of impurities, allowing the crystals to grow to a considerable size.
Did porphyry cool quickly or slowly?
Porphyry cooled slowly, allowing large crystals to form within a fine-grained matrix. This slow cooling process gives porphyry its characteristic appearance of large crystals embedded in a finer grained groundmass.
Do borax crystals form faster than salt crystals?
Yes, borax crystals typically form faster than salt crystals because borax crystals have a higher solubility in water compared to salt. This allows borax molecules to come together and form crystals more quickly when the solution cools.
What are the conditions which small and large crystals are likely to form?
Small crystals are likely to form when the solution cools quickly or when there are impurities present that inhibit crystal growth. Large crystals are likely to form when the solution is allowed to cool slowly or when there is a high concentration of solute in the solution.
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.
Do igneous rocks have small crystals large crystals or no crystals?
Igneous rocks can have both small and large crystals, depending on how quickly they cool. If an igneous rock cools slowly beneath the Earth's surface, it can form large crystals, while rapid cooling at the Earth's surface or in an eruption can result in small or no visible crystals.
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.
What are Igneous rocks that have large crystals and small crystals?
Igneous rocks with large crystals are called intrusive rocks, formed from magma cooling slowly beneath the Earth's surface, allowing for large crystals to form. Igneous rocks with small crystals are called extrusive rocks, formed from lava cooling quickly on the Earth's surface, resulting in small crystals due to rapid cooling.
Do igneous rocks have large crystals?
It depends on the cooling rate of the magma. If the magma cools slowly underground, large crystals can form, creating intrusive igneous rocks. If the magma cools rapidly on the Earth's surface, small crystals or glassy textures can result in extrusive igneous rocks.
What factor determines if an igneous rock has no crystals small crystals or large crystals?
The rate at which the magma cools determines the size of crystals in an igneous rock. Slow cooling allows for large crystals to form, while rapid cooling results in small or no crystals. Other factors such as mineral composition and pressure can also influence crystal size.
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.
How does crystallization form?
crystals form from molten rock as the molten rock cools. if the molten rock cools very fast then you may have small crystals growing or no crystals at all. if the molten rockk colls slowly then you then you have large crystals growing. this happens when the molten material is deep in the earth. examples of these types of crystals are Rubies, Emeralds, and Diamonds. crystals may also form when water is evaporated. salt crystals are an example as they form when salt water evaporates.
