WebThe oceanic lithosphere becomes systematically older as it moves away from the spreading centers at mid-ocean ridges, as you can see in the heat map below: Figure 2.4.5. Age distribution of the oceanic lithosphere. All of this means that the older, denser, and colder plate at an oceanic-oceanic convergent boundary will always subduct into the ... WebDivergent plate boundaries are locations where plates are moving away from one another. This occurs above rising convection currents. The rising current pushes up on the bottom of the lithosphere, lifting it and flowing laterally beneath it. This lateral flow causes the plate material above to be dragged along in the direction of flow.

WebThe lithosphere is the outermost layer of the Earth’s surface. It is rugged, dense, and mostly made out of solid rock. Generally speaking, Earth is made of a really hot core and layers of rock that get colder the farther you move from the center. The lithosphere is the farthest layer from the core and so is the coldest, made of mostly solid rock.
