WebSedimentary rocks form on or near Earth’s surface. Eroded particles of rock are transported by wind, water, and ice and deposited on dry land, on the beds of rivers and lakes, or in the seas. Over years, these pieces of rock, or sediments, are pressed together by the weight of new deposits on top of them and cement together to form rocks ...

They are sometimes exposed at the surface, but often they are buried under miles of rock and sediment. The basement rocks lie below a sedimentary platform or cover, or more generally any rock below …
WebGeologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks.
