The names given to clastic sedimentary rocks are, in large part, determined by the physical characteristics of the particle size rocks' clasts. Mud-sized clasts are very small, less than 0.06 mm in diameter. Sand grains are between 0.06 and 2 mm. Gravel (granule) has a larger range, from 2 to 4 mm. Pebbles are 4 to 64 mm. Cobbles are 64 to 256 mm. Clasts larger than cobbles are classified as boulders. Clastic sedimentary rocks can also be identified by the characteristic of clast sorting. If most of a rock's clasts fall within only one or two of the particle size classes above, the grains of the rock are said to be well sorted. Review the statements below. Two of these statements are true of conglomerate sedimentary rock similar to the one shown in the Gigapan image. Select the two correct statements. Select the two that apply:A. The sediments that make up this rock are well sorted. B. Many of the clasts within this rock are larger than sand. C. Sedimentary rocks like this one are made mostly of sand grains. D. Many of the clasts in this rock have rounded edges.
