Erosion: erosion is the wearing away of the earth"s surface by the action of water, wind, and other natural forces. Erosion can create different landforms, such as valleys, cliffs, and mountains. Rocky sediments: rocky sediments are pieces of rock that have been broken down and transported by natural forces, such as water or wind. These sediments can be found in a variety of locations, such as riverbeds and beach shores. Ocean sediments (with marine fossils) lifted above sea level: ocean sediments that contain marine fossils can sometimes be found above sea level, indicating that the earth"s surface has changed over time and that these sediments were once underwater.
