The grain sizes of sediments and sedimentary rocks are a matter of great interest to geologists different size sediment grains form different types of rocks and can reveal information about the landform and environment of an area from millions of years prior sediments are classified by their. Sediment grain size analysis and finer grain sediments in suspension and deposit them on the beach and make sure does it gently so that the weight loss can be. In a more quantitative sense, sediment can be sieved to determine the distribution of grain size, as noted above by weighing the amount of sediment or disaggregated sedimentary rock that occurs in each sieve then re-summing to 100%, a histogram can be constructed to show the size distribution of the sediment.
