The continents are embedded in the plates. Many continents occur in the middles of plates, not at their boundaries or edges. … Plates are composed of the Earth’s crust and upper mantle, which are collectively called the lithosphere. This layer is like an eggshell compared to the total thickness of the Earth.

What is it called when one plate moves under another?

When an ocean plate collides with another ocean plate or with a plate carrying continents, one plate will bend and slide under the other. This process is called subduction. A deep ocean trench forms at this subduction boundary.
