Lithospheric plates are . a. floating on the asthenosphere b. moved by convection currents in the mantle c. generated at spreading centers d. incorporated into the mantle at subduction zones e. All of the above are correct.

E

Explanation:

The uppermost part of the mantle is called the asthenosphere which is made up of solid rocks know as the lithospheric plate that is flexible and floats linearly. Inner pressure and temperature conditions results in convection current set up inside the crust (mantle) causes radiation of heat outwards and results to drifting of the lithospheric plates.

Also, Plate movement is said to be driven by a combination of the movement of the seafloor away from spreading ridges due to changes in topography and density variation in the crust. While density increase newly formed crust cools and moves away from the ridge.

In addition, Subduction is a geological process where one lithospheric plate moves under another and is forced to sink due to high gravitational potential energy into the mantle. Regions where this process occurs are known as subduction zones
