Will earth become one single land mass soon?
Not “soon” that’s guaranteed. Yes, the land of the Earth is based upon “plates” that move due to Continental Drift made of of trenches and, over time, may move apart (ocean creations), together (mountain creations) or slide past each other causing earthquakes (Western Turkey and San Francisco for example have sliding plates). Once, about 180 million years ago in the Juarrassic Age, the land mass was believed to be an entire continent called Pangea. Through time the plates moved likely causing many earthquakes creating mountains and oceans. Look at an Atlas. Brazil fits perfectly into Western Africa, as does the Gulf of Mexico into the north western African land mass. These are only 2 examples of the hordes of examples anyone can find on an atlas that proved it did happen. In your lifetime, the land you’re on now will have moved about 10 metres from birth to death, as an idea of how slow the process is. Now, what the hell will happen in, say 180 million years from now no one knows – but
