they are both rocks but both formed different ways chalk is formed by dead sea creatures skeleltons build up to form chalk and limestone is formed by shells and very littke amounts of mud and sand
Chalk is a soft, porous rock composed of microscopic coccoliths, whereas limestone is a harder, more dense rock made up of larger calcium carbonate crystals. Chalk tends to form in marine environments with high biological productivity, while limestone forms in areas with high sedimentation rates and pressure.
Chalk is CaCO3. The chemical name for chalk is calcium carbonate. It is a porous sedimentary rock, and is also a type of limestone. The White Cliffs of Dover are actually made from chalk.
Chalk is calcium carbonate, a salt, but it is mildly basic.
Calcium carbonate is commonly known as chalk, limestone, or marble.
Limestone, chalk, and cement primarily consist of calcium carbonate. Limestone and chalk are composed mainly of this compound, while cement typically contains a mixture of calcium silicates, aluminates, and ferrites that are produced by heating limestone and other materials together.
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.

Yes,!! Chalk is fine grains of limestone compressed together and limestone is sedimentary, so chalk has to sedimentary.
No, limestone is harder than chalk. Limestone is a sedimentary rock composed mainly of calcite, whereas chalk is a soft, porous sedimentary rock composed mainly of calcium carbonate.
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.
Chalk is a school supply that is made of limestone. Limestone is ground into a fine powder and used to make chalk sticks which are commonly used on chalkboards.
Hello I deleted the answer... Your welcome DB
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!
Chalk is a type of limestone. Limestone and coal are both organic sedimentary rocks.
Chalk is limestone or calcite, calcium carbonate or CaCO3
