The size of a mineral's crystals primarily depends on the rate of cooling of the molten rock from which they form; slower cooling allows for larger crystals to develop, while rapid cooling results in smaller crystals. Additionally, the availability of space for crystal growth and the concentration of mineral components in the surrounding environment can also influence crystal size. Other factors, such as pressure and temperature conditions during formation, play a role as well.
Yes, some minerals can be identified by their distinctive smell, such as sulfur which has a strong odor. Additionally, size can sometimes be used to determine certain minerals, for example, large crystals are often associated with minerals like quartz or calcite. However, size alone is not typically a definitive characteristic for mineral identification.
Needle-like crystals are long, thin crystals with a shape similar to that of a needle. They typically have a pointed end and may be found in various substances such as minerals, salts, or chemical compounds. These crystals can vary in size and color, depending on the specific substance they are composed of.
The texture depends on the size and shape of the crystals you see in it. The larger the crystals, the slower the rate of cooling. This suggests that it is an intrusive rock. Smaller crystals suggest more rapid cooling indicating that it is an extrusive rock. INTRUSIVE- cooled inside the earth and had more time to create crystals EXTRUSIVE- cooled on the surface of the earth and created small crystals
most minerals have a distinctive crystal arrangement. those minerals that do not have their atoms arranged in crystals are called amorphous minerals.
it depends on how long is ban under the ground
Depends on the particular purplish crystal. Amethyst is not too expensive but other purplish crystals expensive. So it depends.
evaporation
The rate at which magma cools determines the size of the mineral crystal.
Most minerals form crystals.
Most minerals form crystals.
The crystals in a rock are often referred to as mineral crystals. They are formed as the molten rock cools and solidifies, allowing minerals to crystallize and grow within the rock. The size, shape, and arrangement of these crystals can provide clues about the rock's formation and history.
If the lava cools quickly the crystals will be smaller than if it cooled slowly.
correct! :D
The monetary value of crystals and minerals found in rocks depends on their appearance and rarity to collectors, and on their economic significance to the general market for a particular type of mineral.
Depends on the size, redness, and if it is a star ruby.
mineral crystals
Depends on the size. And of course quality.
