Once deposited, the grain size and the particle shape affect the primary porosity. Smaller particles and clay minerals can be packed closer together and the resultant pore sizes are smaller and potentially more tabular, with a resultant orientation more parallel to bedding. ... Examples include: rock salt, rock gypsum, travertine (calcite ...Clastic sedimentary rocks have particles that range in size. Their names are based on the grain size and are categorized into three main groups: clay (less than 1/16 mm), sand (1/16 – 2 mm), and gravel (larger than 2 mm). Grain shape ranges from angular to rounded. For example, breccia has angular grains and conglomerate has rounded grains.34.Which symbol represents the sedimentary rock with the smallest grain size?

When applied dry, much of the salt can bounce off of the road or be scattered by the wind of passing traffic. If the salt is applied wet, more of it sticks to the road, and the loss of salt is reduced.
