May 25, 2019 · Sedimentary rocks form at or near the Earth''s surface. Rocks made from particles of eroded sediment are called clastic sedimentary rocks, those made from the remains of living things are called biogenic sedimentary rocks, and those that form by minerals precipitating out of solution are called evaporites.
Metamorphic rocks are formed by subjecting any rock type—sedimentary rock, igneous rock or another older metamorphic rock—to different temperature and pressure conditions than those in which the original rock was formed. This process is called metamorphism, meaning to "change in form".The result is a profound change in physical properties and chemistry of the stone.

Biochemical sedimentary rocks form from sediment derived by biological processes. This typically occurs in the ocean where a variety of atoms float among the water molecules. Ions, such as calcium, magnesium, and potassium, along with trace elements like silicon, fluorine, iron and phosphorous, are used by marine organisms to form their hard
Clastic sediment grains can be round, angular, or inbetween (subangular or subrounded). Breccia is a clastic sedimentary rock that by definition consists largely of angular grains of pebble size or larger. Conglomerate, another sedimentary rock, consists largely of rounded grains of pebble size or larger.
According to Henrik Svensen at the University of Oslo, Norway, "More than 99 percent of all carbon on the Earth''s surface is stored in sedimentary rocks, and heating those rocks with the hightemperature material that comes out of volcanoes is a good way to put a lot of carbon into the atmosphere quickly.
