The specific heat capacity of granite is 0 79 kj kg k and that of marble is 0 88 kj kg k. The streak of a rock is the color of powder produced when it is dragged across an unweathered surface. Marble is opaque in nature. Depending on the properties like hardness toughness specific heat capacity porosity etc rocks are resistant to heat wear impact etc granite is heat resistant wear resistant whereas marble is heat resistant.

Limestone is a type of sedimentary rock formed by the deposition of natural carbonate material whereas marble is a type of metamorphic rock formed by metamorphism of limestone. The internal carbonate crystal structure of limestone and marble are different to each other. The streak of marble is white. Luster of marble is dull to pearly to subvitreous and its fracture is not available.

When it is formed from a limestone with very few impurities it will be white in color. Marble is a non foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time. The strength of marble is 115 00 n mm 2.
