Explanation:Actually, the present shapes of the continents do fit like a jigsaw puzzle forming a giant supercontinent.
But if we mean that why are there empty spaces left if we stick all continents into each other. There are three answers for this.
One: Some of the parts of that continent is not there anymore and had separated from the part where it once was.
- Take for example, the Indian subcontinent. The Indian subcontinent was not connected to the continent of Asia millions of years ago. In fact it was once part of Australia.
Two: The continents we see today are not all that there is. There is more to it hidden beneath the oceans.
- The continental shelf is a piece of the land that is part of the continent and extends all the way into the sea. Some of them even extends hundreds of kilometers from the mainland. Take for example, Southeast Asia. If we drain all of the waters around southeast Asia by just a hundred meters, we will see more land hidden on the sea. This is still part of the continent of Asia. And that is true to many places across the world like the land under the North Sea.
3. Erosion
- The last supercontinent had existed 250 Million Years ago. In those timescales, a lot has happened. Oceans have been closed. Storms had come and go. Glaciers marched up and down the poles during the ice ages. And rivers and lakes cut the Earth like hot knife through butter. And then there is life contributing to erosion.
