The Nazca Plate is being slowly consumed as it dives deeper and deeper into the Earths mantle. How do plate tectonics support continental drift? We'll look at different types of plates and their properties, including density and buoyancy, and how it affects the results of plate interactions. Where the two plates meet, the denser oceanic lithosphere of the Nazca Plate is forced down and under the more buoyant continental lithosphere of the South American Plate, descending at an angle into the mantle in a process called subduction. Basics about the Different types two crusts ( the first comprehensive overview of a crust. These plates consist of smaller sub .
