Welcome to our exciting journey into the past to learn about Pangea! Have you ever heard of Pangea? If not, you’re in for a treat because today we’re diving into the story of this incredible supercontinent.
Pangea was a supercontinent that existed around 280 million years ago. It was called a supercontinent because it was made up of all the continents on Earth at that time, joined together into one enormous landmass.
The Earth’s crust isn’t just one big piece; it’s made up of several sections called tectonic plates. These plates move very slowly, about as fast as your fingernails grow. Over millions of years, their movements can change the Earth’s surface dramatically, which is how Pangea came to be.
The word “Pangea” means “all lands” in Greek. Imagine the Earth as a giant puzzle with all the pieces fitting perfectly together to form one massive landmass. That’s what Pangea looked like. Back then, the continents were in different places, and there was only one big ocean called Panthalassa.
Pangea formed through a process called plate tectonics. The Earth’s crust is made up of plates that move on top of the Earth’s mantle, a layer of hot molten rock beneath the crust. These plates sometimes move apart, come together, or slide past each other.
About 300 million years ago, all the continents were in the Southern Hemisphere and began moving closer together. Over millions of years, they collided and formed the gigantic landmass known as Pangea.
Pangea looked very different from today’s Earth. It had huge mountain ranges like the Appalachian Mountains in the United States and the Ural Mountains in Russia. There were also vast deserts like the Sahara Desert in Africa and large inland seas like the Permian Sea.
Pangea didn’t last forever. About 200 million years ago, it started to break apart. The Earth’s plates kept moving, and Pangea split into two smaller landmasses: Laurasia in the north and Gondwana in the south. Over millions of years, these landmasses also broke apart, forming the continents we know today.
North America, Europe, and most of Asia were once part of Laurasia, while South America, Africa, Australia, Antarctica, and India were part of Gondwana.
You might wonder how scientists know about Pangea if it existed so long ago. They’ve studied rocks and fossils from different parts of the world to piece together what Earth looked like millions of years ago. Similar rock formations and fossils found in places now far apart suggest these places were once connected.
For example, the same type of dinosaur fossils have been found in both Africa and South America, even though these continents are now separated by a large ocean. This suggests they were once connected as part of Pangea.

Welcome to our discussion about Pangea! Have you ever heard of Pangea? Well, you’re in luck because today we are going to talk all about it.
Pangea was a supercontinent that existed around 280 million years ago. It is called a supercontinent because it was made up of all the continents on Earth at the time, joined together in one huge landmass.
You see, the Earth’s crust is not one solid piece; it is made up of several different sections called tectonic plates. These plates move around very slowly, about the same speed that your fingernails grow. But over millions of years, their movements can make huge changes to the Earth’s surface, which brings us back to Pangea.
Here’s an interesting fact: the word Pangea actually means “all lands” in Greek. Imagine the Earth as one big puzzle with all the pieces fitting perfectly together to form one giant landmass. This is what Pangea looked like. The Earth was very different back then; the continents were in different places, and there was only one big ocean called Panthalassa.
So, how did Pangea form? It all started with a process called plate tectonics. As we mentioned earlier, the Earth’s crust is made up of several different plates that move around on top of the Earth’s mantle, which is a layer of hot molten rock beneath the crust. Sometimes the plates move apart, sometimes they move towards each other, and sometimes they slide past each other.
About 300 million years ago, all the continents were located in the Southern Hemisphere, and they started moving closer together. Over millions of years, they collided and formed one huge landmass: Pangea.
Pangea looked very different from the Earth we know today. There were huge mountain ranges like the Appalachian Mountains in the eastern United States and the Ural Mountains in Russia. There were also vast deserts like the Sahara Desert in Africa and huge inland seas like the Permian Sea.
But Pangea didn’t last forever. About 200 million years ago, the supercontinent started to break apart. The Earth’s plates continued to move, and eventually, Pangea split into two smaller landmasses: Laurasia in the north and Gondwana in the south. Over millions of years, Laurasia and Gondwana also broke apart, forming the continents we know today.
North America, Europe, and all of Asia (except for India) were once part of Laurasia, while South America, Africa, Australia, Antarctica, and India were part of Gondwana.
Now, you might be wondering how we know about Pangea if it existed so long ago. Well, scientists have studied the rocks and fossils found in different parts of the world to piece together what the Earth looked like millions of years ago. They have found similar rock formations and fossils in places that are now very far apart, which suggests that these places were once part of the same landmass.
For example, the same type of dinosaur fossils have been found in both Africa and South America, even though these continents are now separated by a large ocean. This suggests that Africa and South America were once connected as part of Pangea. Scientists have also discovered DNA evidence that links humans from different continents to each other. Talk about a small world!
Now that we have learned more about Pangea, let’s review:
Fill in the blank: Pangea was considered a ________ continent because it was so huge.
True or False: Scientists have found similar fossils and DNA evidence on different continents.
When Pangea first split, it divided into how many pieces?
Great job, friends! Pangea was a supercontinent that joined all seven continents together in one giant landmass and reminds us that we are all connected as humans on Earth. What is something new that you learned about Pangea today?

Let me know if you need any further modifications!
Pangea – A supercontinent that existed around 300 million years ago, where all the Earth’s landmasses were joined together. – Scientists believe that Pangea began to break apart about 175 million years ago, leading to the formation of the continents we know today.
Supercontinent – A massive landmass that consists of multiple continents joined together. – Pangea is the most famous example of a supercontinent in Earth’s history.
Tectonic – Relating to the structure and movement of the Earth’s crust. – Tectonic activity can cause earthquakes and the formation of mountains.
Plates – Large pieces of the Earth’s crust that move and interact with each other on the surface. – The movement of tectonic plates can create volcanoes and earthquakes.
Crust – The outermost layer of the Earth, which is solid and relatively thin compared to other layers. – The Earth’s crust is where we live and where all landforms are found.
Mantle – The thick layer of the Earth located between the crust and the core, made of semi-solid rock that flows slowly. – The mantle’s movement is responsible for the shifting of tectonic plates.
Fossils – Remains or traces of ancient living organisms preserved in rock. – Fossils help scientists understand what life was like on Earth millions of years ago.
Continents – Large landmasses on Earth’s surface, such as Africa, Asia, and Europe. – The continents were once part of a single supercontinent called Pangea.
Ocean – A vast body of saltwater that covers most of the Earth’s surface. – The Pacific Ocean is the largest and deepest ocean on Earth.
Landscape – The visible features of an area of land, including its physical elements like mountains, valleys, and rivers. – The landscape of the Grand Canyon is shaped by the Colorado River and millions of years of erosion.
