Once material is weathered from rocks, it is transported away and later deposited somewhere else, and eventually is turned into new rocks. Such rocks are called sedimentary rocks , and they're the subject of this lecture.
Sediments are loose particles of former rocks.
After these sediments are deposited, they may be buried and undergo a set of physical and chemical changes which turn them into solid rock. Rocks formed from sediments are called sedimentary rocks. Diagenesis We will illustrate these processes with clastic rocks, then discuss chemical and biochemical rocks. We discussed weathering last time, so I'll skip to transport. All these modes can transport clastic particles of various sizes, and the size each can transport depends on the force with which it flows.
