Probably because the subsurface ice in a glacier has recrystallized, much as the minerals in some sedimentary rock do when undergoing metamorphism.
A metamorphic rock.
A metamorphic rock is formed when sedimentary rock is subjected to heat and pressure!
it is a metamorphic rock
metamorphic.
Probably the metamorphic rock phyllite.
Geologists classify metamorphic rocks by the arrangements of the grains that make up the rocks.
Yes.
Metamorphic rock is formed deep in the Earth's crust under tremendous heat and pressure. Fossiles are formed in sedimentary rock near the surface.

No banding or alignment of a metamorphic rock's minerals would be consider non-foliated.
Probably orthoquartzite, although some consider it a metamorphic rock.
Metamorphic foliation is a preferred orientation of mineral grains within a metamorphic rock caused by pressure during metamorphism. This alignment creates a parallel arrangement of minerals, giving the rock a layered or banded appearance. Foliation helps geologists understand the history and deformation conditions of rocks during metamorphism.
Yes they are. Structural geologists commonly use them to estimate the strain that the rock has undergone by measuring their change in shape.
A metamorphic rock.
in a metamorphic rock you find rock.
Chert is NOT a metamorphic rock.
No.
