You are really going to confuse people if you use that spelling, but I figured out that you mean chalk and coal. I would describe their type as biological. Chalk derives from the shells of tiny marine organisms, and coal is a residue of plant matter.
Chalk is a biochemical sedimentary rock.
None of the above. Marble is a metamorphic rock.
They are called organic sedimentary rocks, such as coal and chalk.
Yes, it's a sedimentary rock composed of calcium carbonate. Classroom chalk is not necessarily the same as chalk the rock, since it may include binders and pigments in addition to pure calcium carbonate.

Chalk is a biochemical sedimentary rock.
Chalk does not belong to a rock group. Chalk is a type of sedimentary rock composed mainly of the mineral calcite.
None of the above. Marble is a metamorphic rock.
They are both organic sedimentary rocks.
Chalk is a type of limestone. Limestone and coal are both organic sedimentary rocks.
Sedimentary rock, such as limestone, chalk, slate and sandstone.
Limestone and chalk.
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.
They are called organic sedimentary rocks, such as coal and chalk.
Chalk can be used as a sedimentary rock for right and coal as the same type of rock, but for fuel.
Yes, it's a sedimentary rock composed of calcium carbonate. Classroom chalk is not necessarily the same as chalk the rock, since it may include binders and pigments in addition to pure calcium carbonate.
ORGANIC SEDIMENTARY ROCK`s : Is a type of sedimentary rock because sedimentary rock has three types of sedimentary rock called clastic , chemical , and organic sedimentary rock so yes ORGANIC SEDIMENTARY ROCK is a type of sedimentary rock..........................................
