According to the theory, the lithosphere is around 100 km thick and it overlies a molten layer (known as aesthenosphere). The lithosphere is broken up into several large plates called tectonic plates. These plates are in constant motion. The collision, divergence and...
Can you please explain the theory of relativity? Why is time a scalar quantity if you can use it in a past/future manner? Why do weather satellites circle the earth at different altitudes? How would you explain the Cenozoic evolution of the No...
It has long been recognized that the properties of the Cook-Austral chain (Fig. 1) of volcanoes in the South Pacific are difficult to reconcile with the theory that volcanic activity in plate interiors is produced by the drift of tectonic plates over narrow, stationary plumes of hot mantle ...

Soon after the plate tectonics theory was established, subducting slabs were recognised as a fundamental driver of flow in the Earth’s mantle1,2,3. The sinking of oceanic lithosphere indeed induces mantle flow through viscous drag associated with slab down-dip motion4and through a pressure change...
My second theory: by the time he sobered up and realised it wasn't funny after all, there wasn't time to draw a new comic. Although I could draw one of these in five minutes (lettering takes longer), so that doesn't work. Maybe he's ill, badly ill. rja.carnegie@excite.com141.10...
Si's specialty is an area of condensed matter physics that grew out of the discovery more than 20 years ago of high-temperature superconductivity. In 2001, Sioffered a new theoryto explain the behavior of the class of materials that includes high-temperature superconductors. This class of materi...

After describing all the contradictions associated with the current Plate Tectonics theory, this paper proposes a model where a single cause can explain all geophysical and geological phenomena. The source of the Earth's activity lies in the difference of the angular velocities of the mantle and ...
theory, continental plate subsides in proportion to the amount it is thinned and subsequently by the rate it cools down. However, seismic and borehole data from continental margins like the Atlantic show that the upper surface of many plates remains close to sea-level during rifting, inconsistent...
