What else can I help you with?
Are the crystals of a mineral are always the same size?
No, the crystals of a mineral can vary in size depending on factors such as growth conditions and the speed at which the mineral forms. Crystals can range from microscopic to very large sizes, even within the same mineral species.
Why do halite crystals always break into smaller crystals of the same shape?
Halite crystals break into smaller crystals of the same shape due to the crystal structure and cleavage of the mineral. Halite has a cubic crystal structure and perfect cubic cleavage, which means it breaks along planes that are parallel to the faces of the cube, resulting in smaller crystals with the same cubic shape.
Are rock crystals the same as quartz?
Yes! Of course! Because they are both crystals.
What causes minerals to form large and small crystals within the same rock?
Variations in pressure, temperature, and cooling rate during the rock formation process can result in different crystal sizes within the same rock. Rapid cooling tends to produce smaller crystals, while slower cooling can lead to the formation of larger crystals. Additionally, the presence of impurities or the availability of space for crystal growth can also influence crystal size within a rock.
What factor determine the size of crystals in metamorphic rocks?
Large mineral crystals that are all about the same size are formed from magma that cooled slowly inside the earth. Small mineral crystals (not identifiable without a microscope) formed from magma that cooled rapidly, on or near the surface of the earth.
Are the crystals of a mineral are always the same size?
No, the crystals of a mineral can vary in size depending on factors such as growth conditions and the speed at which the mineral forms. Crystals can range from microscopic to very large sizes, even within the same mineral species.
Is the cleavage for a mineral always the same for that mineral?
Yes, all different samples of that mineral will have the same cleavage.
Is the cleavage for a mineral is always the same for that mineral?
Yes, all different samples of that mineral will have the same cleavage.

Do the Swarovski pearls from the Bridal affordable jewelry set come from the same place as the Swarovski crystals?
Yes, the same company makes the pearls as the crystals.
Why is the color or a mineral not a reliabe physical characteristic?
The same mineral can come in a variety of colors and different minerals can be the same color.
Which is a factor that effects the size of mineral crystals formed in magma?
fluoresence is not a factor. I had this same question and i got fluorescence as a correct answer
Are rock crystals the same as quartz?
Yes! Of course! Because they are both crystals.
Is true or false that the crystals in each mineral are the same shape?
Crystals of a certain mineral have a regular formation of atoms. However, crystals of the same mineral can grow differently. The presence of trace minerals, variations in heat, pressure, and the space that they have to grow in can influence the shape of a crystal. Crystalline structures demonstrate characteristic geographic variations for these reasons.
Which property will not always match a mineral's visible color?
The 'streak', or powdered mineral, will not always match the specimen's observed color.
What causes minerals to form large and small crystals within the same rock?
Variations in pressure, temperature, and cooling rate during the rock formation process can result in different crystal sizes within the same rock. Rapid cooling tends to produce smaller crystals, while slower cooling can lead to the formation of larger crystals. Additionally, the presence of impurities or the availability of space for crystal growth can also influence crystal size within a rock.
Which is not a factor that effects the size of mineral crystals formed in magma?
The composition of the minerals is not a factor that affects the size of mineral crystals formed in magma. The factors that do affect crystal size include cooling rate, amount of water present, and amount of pressure.
