Andesite vs Coal

Andesite vs Coal 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 Andesite and Coal Reserves. Andesite is a dark, fine-grained, brown or greyish intermediate volcanic rock which is a commonly found in lava. Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds. 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 Andesite vs Coal information and Andesite vs Coal characteristics in the upcoming sections.

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

Andesite is available in bluish - grey, grey, pink, yellow colors whereas, Coal is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Andesite is Dull and Soft and that of Coal is Veined or Pebbled. Properties of rock is another aspect for Andesite vs Coal. The hardness of Andesite is 7 and that of Coal is 1-1.5. The types of Andesite are Icelandite whereas types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Andesite is white while that of Coal is black. The specific heat capacity of Andesite is 2.39 kJ/Kg K and that of Coal is 1.32 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Andesite is heat resistant, pressure resistant, wear resistant whereas Coal is heat resistant.
