Explanation:
The theory of plate tectonics was immediately recognized as the explanation for the moving continents. It provided a more scientific background as why continents drift apart and the seafloor keeps spreading. 
- The theory explains that the earth is broken up into series of slabs called lithosphere which moves on the weak, ductile and fluid asthenosphere. 
- The movement of part of the earth mantle provided the mechanism through which the lithosphere moves. This is now known as the mantle convection.

- It was immediately accepted when the theory was propounded by Alfred Holmes in the 1930s
