Answer 1

9. including iner Describe the Mechanics of plate tectonic theory the driving force behind the plate movement. Answer :- The concept of plate tectonics brought by Mckenzie and parker in 1967 after the concept of sea floor Spreacling - A tectonic plate (lithospheric plate) is massive irregularly shaped slab of solid rocks generally of both the continental A lithospheric & Oceanic lithosphore, plates move horizontally over the asthenosphere as siged units. The lithosphere includes the crust and the top mantle with s-100 km range of thickness, in oceanic parts and upto 200 kms in Continental area plate may be oceanic or continental clepencling upon the thickness. The lithosphere is broken into seven very large continental and ocean sized plates, and seven medium sized regional plates and many small ones. there are three types of plates 1 Convergent plate :- which on converge one Plates in another 2) divergent which slip past one another plates. and 3) Transform forces & Most scientist believe it u conventive cell or Converctive flow behind Plate tectonic, mobile rock beneath move circular the heated material rises up to the surface spreads & begins to cool. & Sinks back to cleeper depth.
