Mineral like oxides have amorphous stracture.Example alumunium oxide.
Opal is an amorphous form of silica related to quartz, a mineraloid form, not a mineral. A mineraloid is a mineral-like substance that does not demonstrate crystallinity.Now you get it?
Amorphous sediment is sediment that lacks a defined crystalline structure. It can consist of disorganized mineral grains, organic matter, or other materials that do not exhibit a regular geometric arrangement. Examples include volcanic glass shards and organic debris in marine sediments.
because amorphous solids are that solids that don't have geometrical shape and don't have particular melting point but crystalline solids have characterstic geometrical shape and have sharp melting point.
Opal, being amorphous, is not really a mineral but a mineraloid. One of the scientifically accepted standards defining a mineral is that a mineral must have a crystal structure, which opal lacks. Many scientific groups and references, including the acclaimed Dana's System of Mineralogy, categorize Opal together with the "true" minerals. For this reason, Opal -- as well as other amorphous types that fall under the definition of a mineraloid.
Glass is an example of a solid that is amorphous (lacks a regular crystalline structure) and brittle (easily breaks or shatters when subjected to stress).
By definition, a mineral must have a definite crystalline structure. Calcite has this. Glass is amorphous, meaning it does not have such a structure.
Amber is not a mineral, because it has an organic origin and amorphous structure (no orderly internal arrangement of atoms).
No, volcanic glass is not a mineral group. It is a type of igneous rock formed from the rapid cooling of lava without the time for crystallization to occur, resulting in an amorphous (non-crystalline) structure.
Opal is an amorphous form of silica related to quartz, a mineraloid form, not a mineral. A mineraloid is a mineral-like substance that does not demonstrate crystallinity.Now you get it?
Rocks that are classified as non-crystalline or amorphous, such as obsidian, cannot be metamorphosed because they lack a defined crystalline structure. Metamorphism requires heat and pressure to rearrange the mineral structure of rocks, which cannot occur in amorphous materials.
Glass is amorphous in structure, meaning it lacks a regular, repeating pattern of atoms found in crystalline materials.
A solid material with no crystal structure is called amorphous.
Amorphous sediment is sediment that lacks a defined crystalline structure. It can consist of disorganized mineral grains, organic matter, or other materials that do not exhibit a regular geometric arrangement. Examples include volcanic glass shards and organic debris in marine sediments.
An allophane is an amorphous hydrous aluminium silicate clay mineral.
The amorphous rubber is what auto companies use for tires.
Amorphous means not having a distinctive shape or formless. It is no particular mineral or element there for can have no particular melting point.
because amorphous solids are that solids that don't have geometrical shape and don't have particular melting point but crystalline solids have characterstic geometrical shape and have sharp melting point.
