The theory of the continental drift explained how the continents had shifted their original positions. Once all joined together, as a "Urkontinent." Many people thought it was the mountains making them sink, but then that was dismissed because continental rocks were too light to sink to the ocean floor.

Answer:
One cell Theory
Explanation:
As we know that the Single-cell Theory was proposed by George Hadley in 1735, It suggested that Heat at the Equator rises the air columns, and this rising air at the surface creates a belt of Low Pressure and this air at the poles creates a belt of high pressure thereby transferring the energy from equator to the poles. He asserted that the earth is directly over the equator and hence no seasonal variations in the winds exist which came out to be false. He asserted that the earth's surface is uniformly covered with water. But it was later understood that there The high altitude effects distorted this cell activity due to mid-altitude density. The formation of eddies in the oceans was caused due to the impact of Hadley in the polar regions. Also, for this reason, the tropics were considered as the zone of mixing. All these cells could be identified due to their longitudinal orientation.
