The key principle of plate tectonics is that the lithosphere exists as separate and distinct tectonic plates, which float on the fluid-like (visco-elastic solid) asthenosphere. The relative fluidity of the asthenosphere allows the tectonic plates to undergo motion in different directions. Note: That the Indian and Australian plate aren't separated; they are together forming the Indo-Australian Plate      * 1 Synopsis on development     * 2 Key principles     * 3 Types of plate boundaries           o 3.1 Transform (conservative) boundaries           o 3.2 Divergent (constructive) boundaries           o 3.3 Convergent (destructive) boundaries     * 4 Driving forces of plate motion           o 4.1 Friction           o 4.2 Gravitation           o 4.3 External forces           o 4.4 Relative significance of each mechanism     * 5 Major plates           o 5.1 Continental drift           o 5.2 Floating continents           o 5.3 Plate tectonic theory                 + 5.3.1 Explanation of magnetic striping                 + 5.3.2 Subduction discovered                 + 5.3.3 Mapping with earthquakes           o 5.4 Geological paradigm shift     * 6 Biogeographic implications on fauna and flora     * 7 Plate tectonics on other planets     * 8 Metaphoric uses     * 9 See also     * 10 References     * 11 External links
