A longer period of time at a mineral's crystallization temperature and pressure range, will result in increased crystal size. Rocks like granite have visible crystals because the minerals within the rock cooled very slowly underground. Rocks like obsidian have no crystals because they cooled very quickly after eruption above ground.

What does crystal size indicate?
Crystal size can indicate the rate at which a substance cooled or crystallized. Larger crystals suggest slower cooling, allowing molecules more time to arrange in an orderly pattern, while smaller crystals indicate rapid cooling with less time for molecules to organize. Crystal size can also impact a material's properties, such as strength, transparency, and conductivity.
Which crystal can help identify as igneous rock as intrusive or extrusive?
What is the effect of location on crystal size? Label the location of intrusive and extrusive igneous rocks on the diagram below. Then, illustrate the crystal size of the rock formed at that location in the appropriate callout circles.
What affects th size of crystals formed from magma?
the slower the magma cools the bigger the crystal is
What do symmetrical crystal shapes indicate about a mineral?
Symmetrical crystal shapes indicate that the mineral has a well-defined crystal structure with uniform internal arrangement of atoms or molecules. This suggests that the mineral formed under conditions that allowed for ordered growth, resulting in distinct geometric shapes.
When was American Crystal formed?
American Crystal was formed in 1899
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 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 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.
Size of sedimentary mineral crystal grain?
that means like when somthing is in a own properties
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.
What is a soft geometric shape formed by a mineral called?
crystal
What is crystal habit?
== == Many minerals have multiple crystal habits, which are the size and shape of a particular mineral crystals formation. Examples of crystal habit include boytroidal, stubby, blocky, radiating, wheat sheaf, columnar, acicular, foliated, subhedral, euhedral, drusy, dendritic, and bladed.
