fine grained or coarse grained
Grain refers to particle or crystal size in rock.
Grain shape.
Coarse grain
Three characteristics of a rock's grain include size (fine, medium, coarse), shape (angular, rounded), and sorting (well-sorted, poorly sorted). These characteristics can provide information about the rock's origin and history.
texture
A grain can be a tiny piece of rock, yes. A grain can also be a grain of salt, meaning one 'pellet' of salt.
Rock.
An allochem is a grain of rock in a carbonate rock.
yes, it does. when a grain size in an igneous rock is small, it means that it was probably an extrusive rock, meaning it formed on land. but if the grain size is big, it means that the rock most likely formed underground, or it was intrusive. try remembering it like this- the larger the crystals, the more time the rock had to form, and magma cools faster on land, not giving the rocks much time to form.
Marble is has no grain so it is classified as a glassy rock.
