Schists are formed when a sedimentary rock is deformed by great heat and pressure, deep within the Earth's crust. This deformation means that fossils do not survive in schists. Only less deformed rocks, such as slate and shale, can hold fossils.

No. Scoria is rock. It is inedible.
Not necessarily. Most scoria is basaltic, but some can be andesitic.

no, extrusive because it is made by lava not magma.
Scoria is a frothy form of lava ejected from a volcano as individual pieces.
Scoria is a type of volcanic rock that is typically denser than water, so it will sink in water.
Scoria is a highly vesicular (porous), dark colored volcanic rock.
Scoria is a type of volcanic rock that is generally porous and can be permeable depending on its porosity. The vesicles (holes) in scoria contribute to its permeability, allowing fluids to pass through it.
Scoria typically contains minerals such as plagioclase, pyroxene, olivine, and magnetite. These minerals are commonly found in volcanic rocks and contribute to the characteristic appearance and composition of scoria.
