Formation
Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

More about Chalk and Enderbite
Here you can know more about Chalk and Enderbite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Chalk and Enderbite consists of mineral content and compound content. The mineral content of Chalk includes Calcite, Clay, Clay Minerals, Quartz, Sand and mineral content of Enderbite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Chalk vs Enderbite, the texture, color and appearance plays an important role in determining the type of rock. Chalk is available in grey, white, yellow colors whereas, Enderbite is available in black, grey, orange, pink, white colors. Appearance of Chalk is Soft and that of Enderbite is Veined or Pebbled. Properties of rock is another aspect for Chalk vs Enderbite. The hardness of Chalk is 1 and that of Enderbite is 6-7. The types of Chalk are Not Available whereas types of Enderbite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Chalk and Enderbite is white. The specific heat capacity of Chalk is 0.90 kJ/Kg K and that of Enderbite is Not Available. 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 Enderbite is heat resistant, wear resistant.
