Sedimentary rocks have flat layers.
Slate is a type of metamorphic rock. It is a foliated metamorphic rock that has a banded, or layered, appearance due to exposure to directed pressure and heat.
schist
Metamorphic rock is made from a large amount of heat and pressure. Under the serface of the earth this usually takes place very close to the core of the earth, so it is very hot. that creates the heat. Pressure from layers and layers of sediment pileing up, combined with heat, makes a metamorphic rock.
a sedimentary rock, a sedimentary rock is one that has sediments or minerals that create layers this rock is formed when preasure is put upon it.
Foliated rock
Foliated rock has parallel layers.
Sedimentary rocks have flat layers.
That would be sedimentary rock, and (honorable mention) occasionally metamorphic rock.

Foliated.
schist
Foliated is the general descriptive term used to describe the layering or banding of metamorphic rock.

Pressure from layers and layers of sediment pileing up, combined with heat, makes a metamorphic rock.
Those would be non-foliated metamorphic rocks, like quartzite and marble.
