Chalk (limestone) was traditionally used to make the marking devices used on chalkboards, but not the boards themselves. These were made from slate, a metamorphic rock.
Chalk
Sedimentary Rocks because chalk is pretty much limestone.
No limestone and sandstone are sedimentary rocks. Chalk is not.
Chalk is a soft, white, porous sedimentary rock composed of calcium carbonate. It is commonly used in classrooms for writing and drawing on chalkboards. Chalk is also used in various industries, such as agriculture, construction, and art.
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.
Chalk is a form of limestone, a sedimentary rock.
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.
Well, sweetheart, chalk is a soft, white, porous sedimentary carbonate rock, composed of the mineral calcite. It's known for leaving a powdery residue when used on surfaces, making it a popular tool for writing on chalkboards. So, if you're looking for something to scribble your grocery list on the fridge, chalk's your go-to gal.

A sedimentary rock.
Chalk and coal are examples of a kind of sedimentary rock called biochemical sedimentary rock. Biochemical sedimentary rocks form from the accumulation and lithification of organic remains, such as shells and plant material.
No limestone and sandstone are sedimentary rocks. Chalk is not.
Chalk is a soft, white, porous sedimentary rock composed of calcium carbonate. It is commonly used in classrooms for writing and drawing on chalkboards. Chalk is also used in various industries, such as agriculture, construction, and art.
Chalk is a type of limestone. Limestone and coal are both organic sedimentary rocks.
Chalk is a soft, sedimentary rock composed primarily of calcium carbonate, used for writing and drawing. Coal is a hard, dark, combustible rock formed from decayed plant matter, used as a fuel source. chalk is used for writing and coal is used for energy production.
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.
