Earth’s land is never the same, its always shifting due to the collisions and dragging of tectonic plates, therefore its contentiously evolving, even today and it will continue to evolve in the future. We will first start off from 600 million years in past carefully pieced together the map based on years of evidence collected by scientists. These pictures depicts the best possible picture of the world how it looked like in the past and how it will evolve after 100 Million years.

This is how today’s continents are thought to have evolved and will evolve in the future.

Earth 100 Million Years from Now:

Its really amazing to visualize how our earth might look like in 100 Million years. One can only imagine what our civilization will look like in this long period of time. It might look like a lone time for us, but its nothing when compared to the age of the earth which is 4.54 billion years old and it will look even more shorter if you compare it to the age of the universe which is approximately 14 billion years old.
