Definition
Greenschist is a metamorphic rock that is formed under lowest temperatures and pressures and is usually produced by regional metamorphism
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

Etymology
From minerals such as chlorite, serpentine, and epidote, and platy minerals such as muscovite and platy serpentine which are green in color
From Latin conglomeratus, to roll together, i.e. from com together + glomerare to gather into a ball, from glomus (genitive glomeris) a ball

Formation
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.
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

Greenschist vs Conglomerate Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Greenschist vs Conglomerate characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Greenschist and Properties of Conglomerate. Learn more about Greenschist vs Conglomerate in the next section. The interior uses of Greenschist include Bathrooms, Countertops, Decorative aggregates, Entryways, Homes and Interior decoration whereas the interior uses of Conglomerate include Decorative aggregates, Floor tiles and Homes. Due to some exceptional properties of Greenschist and Conglomerate, they have various applications in construction industry. The uses of Greenschist in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Cutting tool, For road aggregate, Roadstone and that of Conglomerate include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Roadstone.
More about Greenschist and Conglomerate
Here you can know more about Greenschist and Conglomerate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Greenschist and Conglomerate consists of mineral content and compound content. The mineral content of Greenschist includes Alusite, Amphibole, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Serpentine, Sillimanite, Staurolite, Talc and mineral content of Conglomerate includes Clay, Sand, Silica, Silt. You can also check out the list of all Metamorphic Rocks. When we have to compare Greenschist vs Conglomerate, the texture, color and appearance plays an important role in determining the type of rock. Greenschist is available in dark greenish - grey, green colors whereas, Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. Appearance of Greenschist is Layered and Shiny and that of Conglomerate is Shiny and Rounded. Properties of rock is another aspect for Greenschist vs Conglomerate. The hardness of Greenschist is 3.5-4 and that of Conglomerate is 2-3. The types of Greenschist are Not Available whereas types of Conglomerate are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Greenschist and Conglomerate is white. The specific heat capacity of Greenschist is Not Available and that of Conglomerate is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Greenschist is impact resistant, pressure resistant, water resistant whereas Conglomerate is heat resistant.
