An epiphyseal plate, more commonly known as a growth plate, is a anatomical structure present at the ends of the long bones of children and adolescents. These plates contain rapidly dividing cells that allow bones to become longer until the end of puberty.
Plate tectonics is the theory that the surface of the earth is broken into larger pieces of crust called plates that ride along on a softer layer of the earth, known as the asthenosphere, which is the upper part of the mantle.ach plate's thickness depends on the type of crust it is made of and the location of the plate. Continental plates can be up to 150 km thick, whereas oceanic plates usually average about 5-10 km thick.
