The sediment is made of fragments of rocks breaking down and weathering at the Earth&#8217;s surface.\n<\/li>\n<li>Chemical sediment &#8211; formed by precipitated minerals, such as rock salt by evaporation of salty water in lakes of shallow seas.\n<\/li>\n<li>Biological sediment &#8211; made of or formed by organisms. Examples include coral reefs and coal made from plant debris.\n<\/li>\n<\/ul>\n<p>When sediment is buried and has water percolating through it it will harden into rock (=lithification). When the sediment is a rock it is a sedimentary rock.\n<\/p>\n<p>\n<\/p>\n<h3><span class=\"mw-headline\" id=\"Clastic_Sediment_and_Sedimentary_Rocks\">Clastic Sediment and Sedimentary Rocks<\/span><\/h3>\n<p>Clastic sediment and sedimentary rocks are described by the size of the fragments.
