Molten magma from the mantle rises at the top oceanic ridge, cools and solidifies, continually forming a crustal plate. Hundreds to thousands of miles from the ridge the plate moves downward into the mantle at the contact with another plate and melts. The continuous process resembling a large "conveyor belt" moves the crustal plate a few centimeters each year.
The seven crustal plates are African Plate, Antarctic Plate, Australian Plate, Eurasian Plate, North American Plate, South American Plate, and Pacific Plate.

The crustal plate found between the Nazca Plate and the South American Plate is the Antarctic Plate.
The movement of crustal plates is driven by convection currents in the mantle. As these currents circulate, they drag the overlying crustal plates with them, causing them to move. This movement can lead to various geological phenomena, such as earthquakes, volcanic eruptions, and the formation of mountain ranges.

Crustal features like mountains, rift valleys, and ocean trenches are directly related to plate tectonics. These features are created by the movement of tectonic plates, which can collide, separate, or slide past each other. The interactions between these plates result in the deformation and creation of various crustal features.
The crustal plates are in constant motion, there is no last movement
The three types of crustal plate movements are convergent (plates move towards each other), divergent (plates move away from each other), and transform (plates slide past each other horizontally). These movements are driven by the interactions of tectonic plates at plate boundaries.
Crustal plate movement due to convection cells occurs in the asthenosphere, which is a semi-fluid layer beneath the lithosphere. The heat-driven convection currents in the asthenosphere cause the overlying crustal plates to move and interact with each other.
