No, Limestone is harder than chalk.
Limestone is a form of calcium carbonate that is softer than marble but harder than chalk. It is commonly used in construction materials and can be found in different shades depending on the mineral impurities present.
Chalk is harder than rubber. Chalk is a form of limestone made of calcium carbonate, which is a relatively hard mineral, whereas rubber is a soft and flexible material typically made from natural or synthetic polymers.
Calcium is the element found in marble, limestone, chalk, and teeth.
No, water from an area with limestone and chalk strata is more likely to be alkaline, not acidic. Limestone and chalk are composed mainly of calcium carbonate which can increase the alkalinity of water through a process called calcification.
Gabbro is harder than limestone. Gabbro is a dense, coarse-grained rock formed from cooled magma, while limestone is a sedimentary rock primarily composed of calcite. Gabbro is more resistant to scratching and weathering compared to limestone.

Chalk is harder than rubber. Chalk is a form of limestone made of calcium carbonate, which is a relatively hard mineral, whereas rubber is a soft and flexible material typically made from natural or synthetic polymers.
A rock that is white and harder than chalk is likely to be marble. Marble is a metamorphic rock that is formed from limestone under high pressure and heat, making it harder and more durable than chalk, which is a soft sedimentary rock.
Diamonds are harder than chalk.
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.
Yes
Yes,!! Chalk is fine grains of limestone compressed together and limestone is sedimentary, so chalk has to sedimentary.
The chemical formula of chalk or limestone is calcium carbonate (CaCO3).
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.
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!
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.
Chalk is a type of limestone. Limestone and coal are both organic sedimentary rocks.
