Hardness, Elasticity, Porosity, Permeability, Density, resistance to diagenesis, conditions of formation. Generalities (this means that in general the following are true and rules don't follow the exception if any exist) Hardness: marble is harder than limestone. It has a higher compressive strength and cohesion. This can get much more technical so let's leave it at that. Elasticity: Young's Modulus, shear modulus of marble is higher. Bulk modulus and poisson's ratio of marble is lower. Porosity of marble is lower. Permeability of marble is lower. Density of marble is higher. Limestone is often altered via fluids and chemical underground and marble isn't. Marble is metamorphic rock and limestone in sedimentary. Marble and Limestone are spelled different.
yes
crushed limestone then it is pressurized so that it for like a solid rock but is not as rigid as a rock because you can write with it on a blackboard.
Blackboards are not scratched by chalk because chalk is softer than the material from which the blackboard is constructed. Sand scratches blackboards because it is harder than the material from which a blackboard is made.
because it consists of small particles that are similar to liquid. Even if we add water to a powdered chalk, it dissolves easily whereas a lump of chalk is harder to dissolve in water.
Limestone is softer than marble, but harder than chalk.
No, Limestone is harder than chalk.
it is becauce of the chemicals present in the acid rain which eats up marble.
Marble is a very hard stone. Even though it is harder than limestone it is not as hard as granite.
rubber is harder than chalk !

Diamonds are harder than chalk.

Chalk is a sedimentary rock composed primarily of Calcium Carbonate. Calcium carbonate is also the number one mineral at the Marble spec. Hardness of Chalk is around 3 Mohs. Granite stay at the number 7 at the Mohs scale and Granite is harder than Marble. Granite is mostly composed by feldspat (christal).
no
CaCO3 is calcium carbonate. Its other mineral names are calcite, chalk, and marble.
Yes
