This is also how fossils form, which is why sedimentary rocks are the only rocks with fossils in them. If a clastic sedimentary rock is formed from clay-sized particles, it is called shale. Sand-sized particles make sandstone, silt-sized result in siltstone, and larger particles make conglomerate rocks.
Breccia forms where broken, angular fragments of rock or mineral debris accumulate. One of the most common locations for breccia formation is at the base of an outcrop where mechanical weathering debris accumulates. Another is in stream deposits a short distance from the outcrop or on an alluvial fan. Some breccias form from debris flow deposits.the visible pieces of sediment it contains. the ocean animals deposited in its layers. the crystals of dissolved minerals it contains. NOT B.
