When we have to compare Chalk vs Lignite, the texture, color and appearance plays an important role in determining the type of rock. Chalk is available in grey, white, yellow colors whereas, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Chalk is Soft and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Chalk vs Lignite. Hardness of Chalk and Lignite is 1. The types of Chalk are Not Available whereas types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Chalk is white while that of Lignite is black. The specific heat capacity of Chalk is 0.90 kJ/Kg K and that of Lignite is 1.26 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Chalk is heat resistant whereas Lignite is heat resistant.
