Crystals that are formed below the surface are formed by the cooling of magma. Crystals above the surface are formed when a volcano erupts, and cools, again, above the surface. Crystals that are below the surface usually have a slower rate of cooling than those above the surface, causing bigger crystals because of the slower cooling:)

What does mineral crystal size tell about how rock formed?
Mineral crystal size in a rock can provide information about the cooling rate of the magma or lava from which the rock formed. For example, faster cooling results in smaller crystal size, while slower cooling leads to larger crystals. This can help geologists determine whether the rock formed deep underground (slow cooling, larger crystals) or at the surface (quick cooling, smaller crystals).
What determines the size of a mineral crystal formed from magma?
The cooling rate of the magma primarily determines the size of a mineral crystal. Faster cooling rates lead to smaller crystals, while slower cooling rates result in larger crystals. Other factors such as the mineral composition and level of nucleation can also influence crystal size.
Do the crystals precipitated from a solution have unique crystal forms?
Crystals precipitated from a solution has unique crystal forms. These are formed with the subsequent growth in its nuclei and the solution contains more solute entities that impacts the crystal formation.Ê
What happens to the size of a crystal when the rate of a cooling igneous rock increases?
When the rate of cooling of an igneous rock increases, the crystal size tends to decrease. This is because faster cooling results in less time for crystals to grow, leading to smaller crystals. Conversely, slower cooling allows crystals more time to grow, resulting in larger crystal sizes.
How does the rate of cooling affect crystal growth in igneous rock?
The most common effect is that more and smaller crystals form than would be formed with slow cooling of the same mass of the same crystalizable material, and the incidence of crystal defects is higher because the rapidity of crystal formation does not permit the correction of initially formed defects by interchange of atoms or other crystal forming units between the liquid and solid phases that can occur during slow crystallization.
What effect does the the the rate that magma cools have on crystal formation?
if lava cools slowly, it will have a lot of crystals. When it cools fast, there will be little to no crystals what s ever.
What factors causes the difference in the size of crystals formed?
The size of crystals formed is influenced by factors such as temperature, cooling rate, concentration of solutes, presence of impurities, and growth conditions. Higher temperatures and slower cooling rates typically lead to larger crystals, while a high concentration of solutes or presence of impurities can inhibit crystal growth. The specific crystal structure and properties desired also play a role in determining the size of crystals formed.

Which is a factor that affects the size of a mineral crystals formed in magma?
evaporation
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.
What is the effect of pressure on the growth of these crystals from a solution?
Pressure can significantly influence the growth of crystals from a solution by altering the solubility of the solute and the rate of nucleation. Increased pressure typically enhances solubility, allowing more solute to dissolve and potentially leading to larger crystal formation. However, excessive pressure can hinder crystal growth by disrupting the orderly arrangement of molecules, resulting in smaller or poorly formed crystals. Overall, the optimal pressure conditions are crucial for achieving desired crystal characteristics.
What factor cause the difference in the size of crystal formed?
weather and climate changes cause difference in size of crystals. or erosion
Do the crystals precipitated from a solution have unique crystal forms?
Crystals precipitated from a solution has unique crystal forms. These are formed with the subsequent growth in its nuclei and the solution contains more solute entities that impacts the crystal formation.Ê
What factors affect the diffusion rate in solid metal crystals?
The diffusion rate in solid metal crystals is influenced by factors such as the temperature of the crystal (higher temperature increases diffusion rate), the presence of defects or imperfections in the crystal structure (such as vacancies or dislocations), and the composition of the metal crystal (alloying elements can affect diffusion rate). Additionally, the crystal structure and grain boundaries can also impact diffusion rates in solid metal crystals.
Do salt crystals form faster than borax crystals?
Well it depends. But im currently growing salt, suagr and borax crystals and my borax crystals formed first. So i guess my answer is No, borax crystals grow faster but dont take my answer as a fact i could be wrong.
How does the rate of cooling affect the size of copper sulphate Chrystals?
Faster cooling rates tend to produce smaller copper sulfate crystals, as they do not have enough time to grow larger. Slower cooling rates allow for more time for crystal growth, resulting in larger crystals. The size of crystals formed is often dependent on the rate at which the solution cools.
