Large mineral crystals can form when magma is able to cool slowly underground, creating intrusive igneous rock.
When magma in a volcano cools slowly that is how it forms a large crystal. If the magma cools quickly it doesn't have time to form a large crystal. That is how it forms.
when the mineral has space to grow freely
A anhedral crystal is not well formed due to limited growth in environment. A euhedral crystal are well formed with recognizable faces from more space to grow.
When minerals solidify they form crystalline structures.
cleavage surface are smooth and shiny as the fracture is due to weakness in the bonds between the atoms rather than a breakage. Crystal face is where the crystal development such as twinning take place.
Quartz is silicon dioxide, SiO2. It forms a hexagonal prism as an ideal crystal. Impurities in the quartz can give it pretty colours eg rose quartz.Halite is sodium chloride, common table salt, NaCl. It forms cubic crystals. These can be seen with a magnifying glass when looking at table salt.Perfect crystals are formed by careful evaporation of solutions.
I believe the answer would be the crystal system, but the crystal system is based on the angles and length of the axis of the crystal. The axis length and the angle at which they meet would affact the number and angle of the crystal faces.
If a mineral belongs to the hexagonal crystal group, then its crystals have six sides.
Mineral crystal faces of varying luster and geometric shapes.
it is the property of solid crystal that they have straight edges and flat faces.
A anhedral crystal is not well formed due to limited growth in environment. A euhedral crystal are well formed with recognizable faces from more space to grow.
In geology, crystals are the geometric shapes into which minerals form. The crystals can be described in terms of axes, angles, and faces, unlike tree bark.
A xenoblast is a crystal forming in a metamorphic rock which has not yet developed its crystalline faces and gets its shape from bordering crystals.
When minerals solidify they form crystalline structures.
cleavage surface are smooth and shiny as the fracture is due to weakness in the bonds between the atoms rather than a breakage. Crystal face is where the crystal development such as twinning take place.
the faces on a crystal...
Faces
Crystal Systems is the word for "observe number and angle of crystal faces."
A crystal is a polyhedral shape. The number of faces (which means the same thing as sides) depends on the crystal.
