Definition
Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel
Greenschist is a metamorphic rock that is formed under lowest temperatures and pressures and is usually produced by regional metamorphism

Etymology
From Old English flint - a type of rock mainly known for high hardness and for giving off sparks when struck
From minerals such as chlorite, serpentine, and epidote, and platy minerals such as muscovite and platy serpentine which are green in color

Formation
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
Greenschist is medium grade metamorphic rock, formed by the metamorphosis of mudstone or shale, or some types of igneous rock, when it is subjected to higher temperatures and pressures.
