What is the theary of plates tectonics?

Answer 1

The theory of plate tectonics was proposed by Alfred Wegener, the theory is that the lithospheric plates move by convection currents from the mantle, this is called continental drift

Answer 2

The theory of plate tectonics states that the Earth's lithosphere (the solid outer layer) is divided into several large plates that move relative to each other. These plates float on the semi-fluid asthenosphere underneath. Plate boundaries are where the plates interact, resulting in processes like earthquakes, volcanic activity, and the formation of mountain ranges. This theory helps explain the distribution of continents, the occurrence of earthquakes and volcanoes, and the formation of oceanic trenches and mountains.
