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
Coal and limestone are both forms of sedimentary rock and are often found together in deposits.
Chalk is a form of limestone composed of the skeletons and secretions of small marine organisms. There are other types of limestone.
The are both formed of carbonate minerals.
the acid that is used in chemical weathering such as acid rain cause the chalk to react to it, the same way rocks do because they have the same chemicals in them
Not much; they're both composed largely of calcium carbonate, CaCO3.
Chalk or limestone: chemical formula is CaCO3 - calcium carbonate.
But the physical and mineralogical properties are different.
Both are chemically calcium carbonate; probable more calcite in chalk.
they are all varieties of limestone
Yes! CaCO3, (calcium carbonate)
Chalk and marble are some other types of limestone.
it is one of the following soap or copper or ; limestone or wood or marble or baking powder or chalk which you need to find
Limestone is softer than marble, but harder than chalk.
Calcium.
Limestone, is impure crystalline Calcium carbonate (CaCO3). Chalk, and Marble are other CaCO3 minerals.
Chalk and marble are forms of limestone. They are all made of Calcium Carbonate.
they all have differentlimestone'swhich makes them have something in common. :D by jessicaxxx

Limestone or dolostone forms marble. This encompasses all types, from Chalk to Oolitic Limestone.
Limestone is calcium carbonate. Marble is limestone. So is chalk powder.
Limestone/chalk. Limestone has been subjected to heat and/or pressure, it metamorposes into marble. Both limestone and marble are calcium carbonate (CaCO3). Its just that the internal physical structure of limestone is altered.
CALCIUMThis element is calcium (Ca).
Limestone is softer than marble, but harder than chalk.
Calcium.
Limestone is calcium carbonate. Marble is limestone. So is chalk powder.
The common name of Calcium carbonate may be Chalk, but chemically that's not true, if it is the blackboard writing chalk. This chalk is actually Calcium sulfate, which is mistaken as Calcium carbonate, as its manufacturing process uses Calcium carbonate.So, I think the common name for chalk should be Limestone, which is the most common mineral form of this compound.
