shells
Organic sedimentary rocks like coal and some limestones, are composed of particles created by life processes. In the case of coal it is plant remains. With limestones, it is the shells and secretions of small marine organisms.
Limestone is non-magnetic.
Usable groundwater is to be found in aquifers. Aquifers are porous, permeable rocks sandwiched between two layers if impermeable rocks. Sandstones and porous limestones can form good aquifers.
it has 7 layers!!
limestones are sedimentery rocks because it is formed by layers.

As it can be used for housing materials which would give us many jobs !
