Sandstone and limestone have been used as building materials for thousands of years because they stand up well to the weather. They are natural sedimentary rocks that can last for thousands of years especially in dry climates like Egypt.
Limestone is a sedimentary rock primarily composed of calcite and aragonite minerals. It often contains fossils or other organic remains. The structure of limestone can vary from fine-grained to coarse-grained, with a range of colors including white, gray, and beige.
There are two main types of limestone: (1) calcitic limestone, which is mainly composed of calcium carbonate, and (2) dolomitic limestone, which contains a combination of calcium carbonate and magnesium carbonate. These types of limestone have different properties and are used for various applications depending on their composition.
Limestone is the parent rock of marble. The word marble can be used to refer to both metamorphosed and unmetamorphosed limestone.
chalk is a very pure form of limestone made of calcite. i think >:P
Gypsum is a very soft mineral made of calcium sulfate dihydrate, chemical formula CaSO4·2H2O. Chalk is soft, white, porous limestone composed calcium carbonate, chemical formula CaCO3.
because it is soft and not breakable
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
Talc and chalk are not the same. Talc is a mineral composed mainly of hydrated magnesium silicate, known for its softness and lubricating properties. Chalk, on the other hand, is a soft, white, porous form of limestone composed mainly of calcium carbonate, commonly used for writing or drawing.
A soft, earthy substance, of a white, grayish, or yellowish white color, consisting of calcium carbonate, and having the same composition as common limestone., Finely prepared chalk, used as a drawing implement; also, by extension, a compound, as of clay and black lead, or the like, used in the same manner. See Crayon., To rub or mark with chalk., To manure with chalk, as land., To make white, as with chalk; to make pale; to bleach.

The common name for a chalk is simply "chalk". It is a soft, white, porous sedimentary rock used for writing or drawing on blackboards or sidewalks.
"Tiza" in Spanish translates to "chalk" in English. It is a soft white or gray rock used for writing or drawing on blackboards or other surfaces.

1. It was available close to the pyramid site 2. Limestone is quite a soft stone so easy to work with copper tools
