Slate
The two textures of metamorphic rocks are the Foliate and Non-foliate textures.
Slate is a foliate metamorphic rock with the smallest crystals. It forms from the low-grade metamorphism of shale or mudstone, resulting in fine-grained crystals too small to be seen with the naked eye.
Any rock can undergo metamorphism, be it sedimentary, igneous or even the transformation of one type of metamorphic rock to another.
Foliation is a descriptive term applied to certain types of metamorphic rocks, so, by definition, Yes, a folate rock is metamorphic.

Yes, a metamorphic rock with no banding is classified as a nonfoliated rock. Nonfoliated rocks do not exhibit the layering or banding commonly seen in foliated rocks due to the recrystallization process they undergo during metamorphism.
Low foliate intake in pregnancy is a particular concern since it is highly associated with an increased risk of the foetus developing Spina Bifida.
A fossil is the preserved traces of a living organism from the past (plant, animal, etc.). It is generally preserved because of fast burial in an oxygen-poor environment with low heat and pressure. A foliated rock is a metamorphic rock that has gneiss banding as a result of high pressure and temeprature
Foliate has to do with leaves. (Hence the foliage of autumn when the leaves turn different colours.) But there are other and quirky definitions of the word, having to do with the coating of a mirror with a thin layer, or to decorate with a thin layer, or to split into thin, leaf-like layers. check the link for more info: http://www.thefreedictionary.com/foliate
No every rock is able to change into anther
Japanese beetles eat the foliate and flowers of plants.
Rhyolite is an igneous rock.
