WebSorting The extent to which all the grains are the same size is known as sorting. If all the grains are the same size, they are well sorted. Some sandstones are well sorted, and some are not. Most conglomerates are poorly sorted, and consist of a mixture of grain sizes ranging from sand to pebble. Webe. all of the above result in poorly sorted sediments. 14. Which of the following statements about graded bedding is true? a. Graded bedding occurs because heavier particles tend to settle out of water faster than lighter particles. b. Graded bedding might occur where a stream channel migrates across its flood plain.

If sediments are well sorted, pore spaces are uniformly sized, thereby allowing for groundwater flow readily between individual sediment particles. If sediments are poorly sorted, pore spaces are filled with smaller sediments, thereby reducing the movement of water through the deposits.
