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.
Limestone or Sandstone are two examples of sedimentary rocks. Two examples of sedimentary rocks are slate (fine silt) and chalk (shell remains of sea creatures).
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.
Limestone, sandstone, mudstone and chalk.
No limestone and sandstone are sedimentary rocks. Chalk is not.
There is Sandstone, Chalk, Coal, Limestone, and Shale.
Sedimentary rock, such as limestone, chalk, slate and sandstone.
Limestone Chalk Calcareous sandstone Dolomite
They are sedimentary rock. Four examples being chalk, sandstone, limestone and slate.
Limestone mostly, sometimes in shale and coal.
There are organic rocks, like Limestone, and clastic (composed of fragments), like Sandstone. Within these groups there are others, like coal is organic and siltstone is clastic, but even within limestone and sandstone, there are further categories. There's oolitic limestone, chalk and 'shelly' limestones; and arkose, desert sandstone, orthoquartzite (generic sandstone), and others. Conglomerate is an interesting one, if you are after a rock that is not 'normal'.
Different sedimentary rocks are, Chalk, Clay, Limestone, Millstone grit, Sandstone, and coal. They are all found in geological ridges in South East England. Sedimentary means that they were laid down by say river / sea beds and over geoloical time has more sediment places over them and compressed into rock. The two other major rock forms are Igneous and Metamorphic. Igneous rock is lava speyed out by volcanoes allowed to cool and form crystalline solids, such as basalt or granite. Metamorphic Rock is sedimentary rock that has been subjecto geoligical heat and pressure, such as Schists , Gneiss, and Marble.
These are some porous rocks: chalk, limestone, sandstone, pumice, scoria.

Yes,!! Chalk is fine grains of limestone compressed together and limestone is sedimentary, so chalk has to sedimentary.
