When water combines with mineral grains, the grains become larger. The increase in size of mineral grains strains the rock material and weakens it.
This is due to the rate of cooling - a slower rate of cooling results in large mineral grains because the molecules had time to maneuver into a crystalline lattice. A faster rate of cooling results in smaller mineral grains because the molecules were locked into place faster and therefore couldn't form the crystalline lattice structures before getting stuck.
The grains will get smaller.
Clay grains
pores
Metamorphic rock may have coarse, flattened, or aligned mineral grains.
Mineral grains are crystals or pieces of crystals that vary widely in chemicalcomposition
Pumice does not have grains.

Minerals may get changed to other minerals forming a new rock. Mineral grains also become aligned in response to the increased pressure.
The grains will get smaller.
Intrusive
A banded mineral is a mineral that has grains that are arranged in a particular pattern of flat layers or forms swirls.
No. Sandstone is not a mineral, it is a rock type.

Metamorphic rock may have coarse, flattened, or aligned mineral grains.
Metamorphic rock with mineral grains arranaged in bands or lamellar planes are called foliated metamorphic rocks.
