* Grain shape: The shape of the grains in a clastic sedimentary rock can vary from angular to rounded. Angular grains are typically found in rocks that have been transported over short distances, while rounded grains are found in rocks that have been transported over long distances.

* Grain size: The size of the grains in a clastic sedimentary rock can vary from clay-sized particles to boulders. The size of the grains is determined by the energy of the environment in which the rock was deposited.

* Sorting: The sorting of the grains in a clastic sedimentary rock refers to the degree of uniformity in grain size. Well-sorted rocks have grains that are all about the same size, while poorly sorted rocks have grains that vary in size.

* Porosity: The porosity of a clastic sedimentary rock refers to the amount of pore space between the grains. Porous rocks have a high percentage of pore space, while non-porous rocks have a low percentage of pore space.

* Permeability: The permeability of a clastic sedimentary rock refers to the ability of the rock to transmit fluids. Permeable rocks allow fluids to flow through them easily, while impermeable rocks do not.
