Coal vs Pumice

Coal vs Pumice Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Coal and Pumice Reserves. Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds. Pumice is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Coal vs Pumice information and Coal vs Pumice characteristics in the upcoming sections.

Coal vs Pumice 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. Coal vs Pumice characteristics assist us to distinguish and recognize rocks.

More about Coal and Pumice

Here you can know more about Coal and Pumice. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Coal and Pumice consists of mineral content and compound content. The mineral content of Coal includes Analcime, Apatite, Barite, Calcite, Chalcopyrite, Chlorite, Chromite, Clausthalite, Clay Minerals, Crandallite Group, Dolomite, Feldspar, Galena, Gypsum, Marcasite, Muscovite or Illite, Pyrite, Quartz, Siderite, Sphalerite, Zircon and mineral content of Pumice includes Aluminum Oxides, Calcite, Carbonate, Iron Oxides, Silica.

Coal is available in black, brown, dark brown, grey, light to dark grey colors whereas, Pumice is available in beige, grey, light green, light grey, pink, white, yellow- grey colors. Appearance of Coal is Veined or Pebbled and that of Pumice is Vesicular. Properties of rock is another aspect for Coal vs Pumice. The hardness of Coal is 1-1.5 and that of Pumice is 6. The types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite whereas types of Pumice are Scoria. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Coal is black while that of Pumice is white, greenish white or grey. The specific heat capacity of Coal is 1.32 kJ/Kg K and that of Pumice is 0.87 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Coal is heat resistant whereas Pumice is impact resistant, pressure resistant.
