Correct Answer - Option 4 : All of the above

The correct answer is All of the above.

  • Plate tectonics is the theory that Earth's outer shell is divided into large slabs of solid rock, called “plates,” that glide over Earth's mantle, the rocky inner layer above Earth's core.

Plate tectonics theory

  • It uses the evidence of Seafloor spreading
  • Herry Hess first attempt to explain the problems of continental drift theory using the plate tectonic mechanism during the 1960s. 
  • The mobile rock beneath the rigid plates is believed to be moving in a circular manner.
  • The heated material rises to the surfacespreads and begins to cool, and then sinks back into deeper depths.
  • This cycle is repeated over and over to generate what scientists call a convection cell or convective flow.
  • Heat within the earth comes from two main sources: radioactive decay and residual heat.
  • Arthur Holmes first considered this idea in the 1930s, which later influenced Harry Hess’s thinking about seafloor spreading.
  • The slow movement of the hot, softened mantle that lies below the rigid plates is the driving force behind the plate movement
  • The plate tectonic mechanism also becomes helpful to explain the mountain building, the origin of the earthquake, and Seafloor spreading
