Weathering begins over land just beside a mountain. Erosion and transport points to the river in the main diagram. A giant arrow points from land to sea overhead. It is labeled transport. Deposition occurs at the end of the river leading into the main body of ocean. New arrow curves down and to the left at a cutout of water and ground layers showing different layers as burial and lithification. The same arrow takes a sharp curve upwards to show uplift. The arrow which showed burial and lithification subdivides and continues straight forward going to the left of the page. Next cutout is an inch after this arrow ends showing mountainous top layer, different ground layers, and magma or melting occurring at the lowest part of 3d cutout. New arrow hugs the left outside corner of this diagram pointing upward to complete the circle of arrows. It says uplift.
Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.
