The most common material that chalkboards are made out of is porcelain enamel. More information about chalkboards can be found at http://www.answers.com/topic/chalkboard
chalk. Chalk is a type of limestone composed mainly of the mineral calcite, which is a sedimentary rock forming in marine environments. Igneous rocks are formed from the cooling and solidification of magma or lava, so chalk is not typically found in igneous rocks.
Sedimentary Rocks because chalk is pretty much limestone.
No, chalk is not an extrusive rock; it is a type of sedimentary rock. Chalk is primarily composed of calcite, derived from the accumulated remains of microscopic marine organisms. Unlike extrusive rocks, which form from lava that cools quickly at the Earth's surface, chalk forms through the accumulation and compaction of sediments over time.
limestone or could be gypsum Could be chalk. Dip it in vinegar. If it fizzes, it might be a sedimentary carbonate rock like limestone or chalk. There is always a possibility it is another kind of sedimentary rock or possibly an extrusive igneous one. Testing is needed to be sure.
Tailor's chalk is a type of chalk that is designed to make temporary markings on cloth. Using this chalk, a tailor can mark where fabric needs to be cut or garments altered. Once the markings are no longer useful, they can be easily brushed off or washed out, leaving no residue behind.
Chalk is a type of limestone. Limestone and coal are both organic sedimentary rocks.

Chalk can be used as a sedimentary rock for right and coal as the same type of rock, but for fuel.
No, chalk is not considered a type of renewable resource. Once it is used, its dust cannot be completely extracted to make more.
Someone would need a broom, tape measure, chalk, saw, drill, drill bits, hammers, nail sets, nail gun, and mallet. Make sure you don't forget the wood.

It depends on what you mean by “these”. If you are referring to the sticks of chalk used for writing or drawing, then yes, we can say they are chalk, or at least they are made of a similar substance. However, if you are referring to the type of soft white rock that is composed mostly of tiny fragments of the calcite shells or skeletons of plankton, then no, we cannot say they are chalk, because they are not natural rocks, but manufactured products. Chalk is a fine-textured, earthy type of limestone distinguished by its light color, softness, and high porosity. Chalk is also the name of a series of strata consisting mainly of chalk. I hope this helps. 😊
because chalk is a type of rock which crumbles.
Chalk is a type of sedimentary rock that is primarily composed of organic material, specifically the calcareous remains of marine microorganisms such as coccolithophores. It is not considered clastic, as it does not consist of fragments of pre-existing rock like clastic sedimentary rocks.
Used Clay to make beautiful pots and to decorate the pots they rubbed rocks together making paint/chalk stuff and used there hands to spread the paint/chalk. they would but it near the fire and around12 hours near the fire it would be hard as a rock and they would use it to carry corn and water and stuff
