Limestone and chalk, together with marble and egg shells, are both impure form of calcium carbonate.
The impurites are different in each substance, but only in small/trace amounts.

What is a clastic limestone called like it's specific name for example chemical limestones are called tufa?
Chalk.
Limestone and chalk are forms of calcium carbonate?
Yes, both limestone and chalk are forms of calcium carbonate. Limestone is a sedimentary rock composed mainly of calcium carbonate, while chalk is a soft, white, porous form of limestone composed of fossilized marine organisms.
Is chalk the same form of limestone?
The chemical formula is identical (CaCO3, calcium carbonate) but the physical and mineralogical properties are different.
Is chalk the same as the rock limestone?
It is pretty much the same. Chalk and limestone are made of the same elements, but to to make chalk they change the limestone a bit. First they change the shape and then make it smooth. I hope that helps!
What is the relationship between limestone marble and chalk?
Limestone, marble, and chalk are all types of sedimentary rocks composed mainly of calcite. Limestone is the precursor to marble when subjected to high pressure and temperature. Chalk is a softer form of limestone made up of microscopic marine organisms.
