When rock changes into metamorphic rock, its appearance, texture, crystal structure, and mineral content change.
the alignment of a mineral structure
By definition, a mineral must have a definite crystalline structure. Calcite has this. Glass is amorphous, meaning it does not have such a structure.
No. Coal is not a mineral for two reasons: it lacks a crystal structure and it is organic.
Hardness, resistance to weathering, texture, mineral composition, color, and porosity.
The internal atomic structure of a mineral most likely determines the mineral's hardness, cleavage and crystal shape.
yes
The internal arrangement of atoms.
Quartz is a mineral that is the most resistant to chemical weathering. Its resistance is due to the structure of the grains that comprise it.
Amber is not a mineral, because it has an organic origin and amorphous structure (no orderly internal arrangement of atoms).
In order to be a mineral, substances need to have fixed internal crystalline structure. Natural glass does not.
Quartz is a mineral that is highly resistant to chemical weathering. Marble is a mineral that is more susceptible to chemical weathering.
The internal atomic structure.
The internal atomic structure.
Chemical Weathering
Using a rock hammer to break the mineral apart I know this because I am a earth science teacher for 15years
