== == The "coarseness" of a sedimentary rock refers to the rock's textural character, and more particularly, the size of grains contained within it. Thus, a conglomerate containing pebble or cobble clasts is coarser than a sandstone containing sand grains.
In the same way, a conglomerate containing boulders is coarser than a conglomerate containing pebbles.
Clastic sedimentary rocks are classified using the Wentworth Scale. The coarsest elements of this scale are the Rudites. Boulder rudites are conglomeratic rocks with grains of diameter greater than 256mm. They are the coarsest element described on the Wentworth Scale.
There is no upper limit to the scale of sedimentary coarseness, since the size of clast which can be preserved in a sedimentary rocks is potentially very large. 'Olistolith' is a term which describes very large clasts often derived from the sub-sea collapse of oversteepened slopes such as are found at continental margins. Sediments containing olistoliths may reasonably be described as the coarsest sedimentary rocks.
Sandstone
Conglomerate is typically the coarsest sedimentary rock, consisting of rounded gravel-sized clasts cemented together.
The bottom layer of a sedimentary rock is called the basal layer. This layer is considered the coarsest in the rock.
Even the coarsest steel wool pad could not remove the burned rice from the pan. The commercial claims that this shampoo can smooth out even the coarsest hair.

The recommended grit size for the coarsest sandpaper to use when sanding rough surfaces is typically around 60 to 80 grit.
A typical bedding setup consists of the heavy and coarsest material at the bottom is the mattress. The mattress is usually made of materials like springs or dense foam that provide a supportive base.
No, the recommended type of sandpaper for initial rough sanding of a wooden surface is medium grit sandpaper, not the coarsest grit available.
You can use a grain mill (used for grinding wheat berries for flour) and set it on the coarsest setting
Coarse sedimentary rocks like conglomerate and breccia are formed from the deposition and lithification of large fragments or particles such as pebbles, cobbles, or boulders. These fragments are often transported by fast-moving currents like rivers or avalanches, which deposit them in layers that later solidify into coarse sedimentary rocks through the process of compaction and cementation.
cake flour, it is ground finer than all-purpose flour, which is a little finer than bread flour. Meal or farina,(for gruel or porridge) is the coarsest grind.
That is a difficult question in that its phrasing leaves the answer uncertain. In terms of soil - there are three classifications of rock particles when defined by particle size. All three have definite size limits. Sand is the largest or coarsest of the three sizes (generally 0.06 mm up to 2mm) while clay is the finest (less than 0.002 mm). The in-between sized particles are called silt (.002 mm to .06 mm). All three are created by the weathering, crushing or chemical breakdown of rock into particles. Normally rock will continue to break down in size over time until a particle is one crystal of one of the various minerals that comprised the original rock formation. So whether the rock particles ultimately become clay, silt or sand is determined by the mineral composition of the originating rock. The coarsest grains of sand often contain more than one crystal of the original mineral and will still become finer over lengthy periods of time. There are also three main types of rock - sedimentary, igneous and metamorphic. But this is the answer to another question so I won't go any further along this topic right now. So I guess the answer to the question is - the surface contains the largest rock particles. That is where we find all three types (as defined by size) - clay, silt and sand. So far we have gone down twelve miles and are still finding some soil, but even so that is a small fraction of the over 3500 miles to go from the outermost surface (ignoring mountains which only add a few miles at most) to the center of the earth. Still, the largest concentration is probably in the first 20-40 feet so the answer remains - the outer surface. Note that the outer surface also includes the sea bed. Sorry - this may not be the exact answer that was sought, but in order to give a better answer, the question must be more precise.
