Sediments are loose Earth<span> materials such as </span>sand<span> that accumulate on the land surface, in river and </span>lake<span> beds, and on the </span>ocean<span> floor. Sediments form by </span>weathering<span> of rock. They then erode from the site of weathering and are transported by </span>wind<span>, </span>water<span>, </span>ice<span>, and </span>mass wasting<span>, all operating under the influence of gravity. Eventually sediment settles out and accumulates after transport; this process is known as deposition. Sedimentation is a general term for the processes of </span>erosion, transport, and deposition. Sedimentology is the study of sediments and sedimentation.<span>

Carbon is very abundant within metals that are dug from the Earth and they can also be seen making up parts of the human body’s bones to make it light weight.
