Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Jadeitite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.

More about Jadeitite and Chalk
Here you can know more about Jadeitite and Chalk. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Jadeitite and Chalk consists of mineral content and compound content. The mineral content of Jadeitite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Chalk includes Calcite, Clay, Clay Minerals, Quartz, Sand. You can also check out the list of all Metamorphic Rocks. When we have to compare Jadeitite vs Chalk, the texture, color and appearance plays an important role in determining the type of rock. Jadeitite is available in black, brown, colourless, green, grey, white colors whereas, Chalk is available in grey, white, yellow colors. Appearance of Jadeitite is Rough and Dull and that of Chalk is Soft. Properties of rock is another aspect for Jadeitite vs Chalk. The hardness of Jadeitite is 3-5 and that of Chalk is 1. The types of Jadeitite are Not Available whereas types of Chalk are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Jadeitite and Chalk is white, greenish white or grey. The specific heat capacity of Jadeitite is 0.95 kJ/Kg K and that of Chalk is 0.90 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Jadeitite is heat resistant, water resistant whereas Chalk is heat resistant.
