Geodynamic Model
The lithosphere is the outermost layer of the geosphere, composed of the crust and upper mantle. It is divided into plates with clearly defined boundaries coinciding with major landforms. The mesosphere is the largest part of the geosphere and corresponds to the part of the mantle that does not form part of the lithosphere. The core is the center of the planet, consisting of an outer core and an inner core.
Age of the Seabed
Research projects have established that the seabed is expanding slowly, with new lithosphere formed on either side of the ridge axis. Paleomagnetism and magnetometers have provided evidence for the Earth's magnetic field and the symmetrical distribution of paleomagnetism bands on the seabed.
Theory of Plate Tectonics
The lithospheric plates are dynamic, interacting at their boundaries and explaining all geological processes. There are three types of boundaries: divergent boundaries, transform boundaries, and convergent boundaries.
