Is Pangea Real????
Okay today my 6th grade science teacher was talking about Alfred Wegener a german Scientist back in the early 1900's he had the theory of Pangea being a real thing when all the Earth's Continents were once together in north and south called Gondwana and Luarasia. But Gondwana and Luarasia is not what he thought. Anyways as i was saying.. I know they didn't have good machinery back in those days but now we have the technology was it once true that Earth's Continents together at a point in time??

Well, Pangea is real in as much as anything else gathered by careful observation and experimentation is real.
The same principles that explain known mountain formation and other geographical structure also tell us about what said features were in the past. By careful extrapolation, we can predict with fairly good certainty of what the Earth's landmasses looked like (and where they were) at any given point in our planet's history.
So, within our current knowledge, the majority of our landmasses were indeed all congregated in one location. Pangea, so to speak...
There are many good sites out there to see Pangea (and other historical tectonic-drift related features)... the following one is a simple, yet elegant one:
http://geology.com/pangea.htm
Pangaea or Pangæa (IPA: /pænˈdʒiːə/[1], from παν, pan, meaning entire, and Γαῖα, Gaea, meaning Earth in Ancient Greek) was the supercontinent that existed during the Paleozoic and Mesozoic eras about 250 million years ago, before each of the component continents were separated into their current configuration.
Paleogeographic reconstructions show Pangaea as a C-shaped landmass that was spread across the equator. The body of water that was enclosed within the resulting crescent has been named the Tethys Sea. Owing to Pangaea's massive size, the inland regions appear to have been very dry. The large supercontinent would potentially have allowed terrestrial animals to migrate freely.
The vast ocean that once surrounded the supercontinent of Pangaea has been named Panthalassa. The break-up of Pangaea took place about 180 million years ago (180 Ma) in the Jurassic Period, first into two supercontinents (Gondwana to the south and Laurasia to the north), thereafter into the continents we have today.[Wikipedis]
Pangaea, as well as the two supercontinents it became - Gondwana & Laurasia, I'm sure may have existed. But one from of evidence 2 figure out if the continents were all 1 landmass would b 2 look @ fossils & the different rock layers, how old they are & stuff.
It was million years ago*. But then the continents drifted away forming the modern day continents and theyre still moving today! Good Luck
Look into Plate Tectonics. This is the study of the movement of the earths crust plates. As they move one will slide under another, or they will rub with a terrible force and cause earthquakes. Check out the link I added, it can explain it MUCH better than I can.
