Figure 1.1 below shows a simplified map of Earth’s current major tectonic plates and their boundaries. The arrows on the map show the direction the plates are moving. Compare the plate tectonics map (Figure 1.1) to the world map (Figure 1.2). Notice that some of the tectonic plates have oceans above them while others are composed of continents. These are the two main types of tectonic plates: continental and oceanic.
What is the name of the oceanic plate that is found between the oceanic Pacific plate and the continental South American plate?

Figure 2 represents the “whole mantle” convection model wherein the convection cells extend from the asthenosphere to the mantle-‐outer core boundary. Notice that at the center of the diagram the arrows point upward. This represents heat transferring upward from the outer core. As the heat moves toward the surface of the Earth, it diverges to form two distinct convection cells. The asthenosphere spreads in opposite directions from the center of the diagram, which causes the lithosphere above it to move apart, creating a ridge. On the outer edges of the convection cells, the lithosphere dives into the Earth, forming trenches. Note that the layers of the Earth are not drawn to scale in Figure 2.
Tension is the stress that causes the lithosphere to pull apart. Where do you see the result of tension in Figure 2?
