Document Summary

Clastic sediments= grains and fragments of weathered rocks. How clastic sediments are categorized sorting sediment= (biggest to smallest) gravel, sand, silt, clay. Deltas and alluvial fans= streams drop the largest particles then the smallest. Glacial deposits= water moves downstream so sedimentary rocks tend to form in lakes and oceans. Aeolian deposition= the depositing of sediments into sand dunes or places without water. Lithification=when sediments pile on top of each other and form into one. Chemical sediments= minerals dissolved in water precipitate out. Banded iron formations= hydrothermal vents where water is rusting because of oxygen.
