Pangaea

Hello there. I have a very old secret to share with you, one that’s bigger than any country and older than any dinosaur. Long, long ago, before there were any people, I was all the land in the whole world, all joined together. Imagine all the places you know from a map, like North America, Africa, Asia, and Europe, all snuggled up like pieces in one giant puzzle. A dinosaur could have walked from what is now Brazil all the way to Nigeria without ever getting its feet wet in an ocean. It was one big family of land. My name is Pangaea, and I was a supercontinent. But I wasn't going to stay that way forever. I was getting ready for a very, very slow dance that would change the world.

For millions and millions of years, nobody knew I ever existed. The pieces of me had drifted so far apart that no one could see how they once fit. Then, a little over one hundred years ago, a curious man and weather scientist named Alfred Wegener started looking very closely at maps. Around the year 1912, he noticed something amazing. The long, curved coast of South America looked like it could fit perfectly against the coast of Africa, just like your puzzle pieces at home. He also found fossils, which are the shapes of ancient plants and animals left in rocks, of the very same creatures on different continents separated by giant oceans. He thought, 'How could this be?'. In his book from 1915, he explained his big idea that all the continents were once connected. He gave me my name, Pangaea, which means 'all lands' in an old language. At first, many other scientists didn't believe him because he couldn't explain how I moved. It wasn't until the 1960s that other smart people figured out the puzzle of plate tectonics, which showed that the ground beneath our feet is always moving, just super, super slowly.

Even though I broke apart about 175 million years ago, my story isn't over. The continents, which were once all part of me, are still drifting today. They move about as fast as your fingernails grow, which is so slow you can't feel it, but it's happening all the time. I am a reminder that our Earth is alive and is always changing in exciting ways. Knowing about me helps scientists understand why we have tall mountains, big earthquakes, and fiery volcanoes. It also shows us that even though we live in different countries separated by huge oceans, we all come from the same place. We are all part of one big, beautiful, moving world that started with me.
