Sedimentary Rocks. Rivers, oceans, winds, and rain runoff all have the ability to carry the particles washed off of eroding rocks. Such material, called detritus, consists of fragments of rocks and minerals.When the energy of the transporting current is not strong enough to carry these particles, the particles drop out in the process of sedimentation.
