Why the continents have tendency to drift away from each other?

Answer 1

There was the single large continent long ago. Now that there are many and they are drifting away from each other. Here goes the probable explanation for the same. The continents was above the sea level. Here goes the simple experiment to explain the same. You put the say about ten logs of wood. Place nine logs on them. Then put eight logs above them. Then put seven logs above them. Then six. I do not go up to one, because there was not a single large hill, in place of the continent. Tie them with a rope and place them on the water. Then cut the ropes. The logs will drift away from each other. There goes the explanation for formation and drifting the continents. They try to go to the centre of the earth due to gravity. The process is slow. Because the gravitational force exerted by the single continent was not too large and the earth below was and is too viscus for rapid movement. The gravitational force is not too large as the height of the continents is not too high as compared to trenches in deep sea. This has to be compared with the distance from the centre of the earth.
