Well sorted rocks contain almost all grains of the same size. Moderately sorted rocks contain particles of relatively similar grain sizes.Conglomerate is a clastic sedimentary rock that contains large (greater than two millimeters in diameter) rounded particles. The space between the pebbles is generally filled with smaller particles and/or a chemical cement that binds the rock together.

Silt and clay make up less than 5% of the rock. Rounded sand-sized grains are approximately 99% quartz and 1% feldspar. Silt and clay make up less than 2% of the rock. Angular sand-sized grains are approximately 70% quartz, 20% lithic, and 10% feldspar.Environment: The rock fragments can be rounded from being rolled along a stream bed or a beach during transportation. If the fragments embedded in the matrix are angular instead of rounded, the rock is called a breccia (pronounced BRECH-i-a). ...

Sandstone is a type of rock made from sediment — a sedimentary rock. The sediment particles are clasts, or pieces, of minerals and fragments of rock, thus sandstone is a clastic sedimentary rock. It is composed mostly of sand particles, which are of medium size; therefore, sandstone is a medium-grained clastic sedimentary rock.Sedimentary Rocks Lesson #13. The land around you, no matter where you live, is made of rock. If you live in a place that has good rich soil, the soil itself is finely broken down or weathered rock.
