Pangea to the Current to the Future: Watch Animations Displaying 500 Million Years of Continental Drift

Issues change…

Espe­cial­ly whenever you’re observe­ing the con­ti­nen­tal transfer­ment from Pangea to the current day in 5 mil­lion years incre­ments on the fee of two.5 mil­lion years per sec­ond.

Wher­ev­er you’re, 350 mil­lion years in the past, your tackle would’ve been locat­ed on the mega-con­ti­nent of Pangea.

Ear­ly people debuted round 200 mil­lion years in the past, which is when the geospa­tial tech com­pa­ny ESRI’s time lapse ani­ma­tion, above, begins.

Right here’s a map of what issues regarded like again then.

Those that’ve grown a bit fuzzy on their geog­ra­phy could require some indi­ca­tions of the place future land­mass­es shaped when Pangea broke aside. Your map apps can’t aid you right here.

The primary cut up occurred within the mid­dle of the Juras­sic peri­od, outcome­ing in two hemi­spheres, Laura­sia to the north and Gond­wana.

Because the mission’s sto­ry map notes, 175 mil­lion years in the past Africa and South Amer­i­ca already bore a resem­blance to their mod­ern day con­fig­u­ra­tions.

North Amer­i­ca, Asia, and Europe want­ed to remain within the oven a bit longer, their famil­iar shapes start­ning to emerge between 150 and 120 mil­lion years in the past.

India peeled off from its “moth­er” con­ti­nent of Gond­wana some 100 mil­lion years in the past.

Its tec­ton­ic plate col­lid­ed with the Eurasian Plate, giv­ing rise to the Himalayas and the Tibetan Plateau, by which level, dinosaurs had been extinct for about 15 mil­lion years…)

Geog­ra­phy nerds could chafe on the appear­ing­ly inac­cu­fee sizes of Inexperienced­land, Antarc­ti­ca and Aus­tralia. Relaxation assured that the map­mak­ers are conscious, chalk­ing it to the “dis­tor­tion of the automotive­to­graph­ic professional­jec­tion that exag­ger­ates areas near the Poles.”

Only for enjoyable, let’s run it again­wards!

However sufficient of the previous. What of the longer term?

Those that actual­ly need to know might leap forward to the top of the sto­ry map to see PALEOMAP Mission founder Christo­pher Scotese’s spec­u­la­tive con­fig­u­ra­tion of earth 250 mil­lion years therefore, ought to cur­hire tec­ton­ic plate movement tendencies con­tin­ue.

Behold his imaginative and prescient of mega-con­ti­nent, Pangea Prox­i­ma, a land­mass “shaped from all cur­hire con­ti­nents, with an appar­ent excep­tion of New Zealand, which stays a bit on the aspect:”

On the oppo­website aspect of the world, North Amer­i­ca is attempt­ing to suit to Africa, nevertheless it looks like it doesn’t have the precise form. It would prob­a­bly want extra time…

To not bum you out, however a more moderen research paints a grim­mer pic­ture of a com­ing tremendous­con­ti­nent, Pangea Ulti­ma, when excessive tem­per­a­tures have ren­dered simply 8 per­cent of Earth’s sur­face hos­pitable to mam­mals, ought to they sur­vive in any respect.

Because the research’s co-author, cli­ma­tol­o­gist Alexan­der Farnsworth, instructed Nature Information, people would possibly do properly to get “off this plan­et and discover some­the place extra hab­it­in a position.”
