Wow, wish I could be around for that!

The interior regions of the merged continents will most likely be more arid than the illustrations portray.
You only have to look to modern Australia as an example of how dry things can be.
The combined Africa and Eurasia shows some kind of subduction zone, which would probably be a mountainous region.
The land to either sides of this mountain chain could well be desolate sands for thousands of miles in every direction.
Not particularly hospitable territory, but not exclusive of life…

How can this be the future Pangaea when the Atlantic Ocean is in fact getting bigger? The Mid-Atlantic Ridge is pushing the Americas and Africa/Europe away from each other, meaning that Russia and Alaska will eventually collide. This picture is actually more of a representation of the Pangaea that existed 250 million years ago. “Pangaea Ultima” will see the expansion of the Atlantic ocean and the collision of Asia and North America, with Australia stuck between them. South America will fold up around the bottom of Asia and India will become part of the greater Asian landmass, producing larger mountains in the Himalayas. Africa will migrate west and meet with South America at the south end of India. The Mediterranean Sea will expand to become its own ocean and the Indian Ocean will cease to exist.

Actually, the person who made this map said that some subduction in the western atlantic would eat up the Atlantic and draw the continents together to close the Atlantic and Indian Oceans into a small ocean basin. Until then, the Atlantic would widen (for ~50 million years).
This map is actually outdated- recent data shows the North American plate actually contains a bit of Eastern Russia and that Antartica will actually wedge itself between South America and Eurasia (Australia will smash into Indochina) before those two continents crush it.
In the end, the Himalayas would look like a dwarf compared to the huge moutain ranges that would rise by the end of all this (Mediterranean Mts, Antartic Mts from colliding with Africa, S. America, and Asia, etc.). In addition, the Indo-Atlantic Ocean will be even smaller than in the picture here thanks to Antartica.
The climate zones will then be fairly easy to define- the entire continent is basically a circle without many major pennisulas (except for Alaska-Kamcamtka), so ocean currents probably will travel predictably (warm water mostly in equitorial, cold water in more extreme latitudes, warm circulation in the central ocean basin). My guess is that this will lead to pretty extreme climate, but earth surely has experienced such hard times before…?

Hello, looking at this map I can easily say that an equatorial rusia seems very wierd! I like this map and the science I’ve read up indicates that my country UK, will be an arctic counrty swamped in boreal forest, aurora will shine in the nights sky, 40 degree summers will be followed by 40 inch snow winters, wow!

what did india look like back then because i am doing a project on pangea.
