My hypothesis was correct

Will the continents reunite again to form Pangea once again?

Scientists believe that if the Plate tectonics keep drifting apart from each other, the seven continents may be united again in a couple of millions of years, to form Pangea, or just one supercontinent once again. For the seven continents(second map) to form Pangea(first map) again, there will have to be great plate movement, earthquakes and volcanic eruptions.

Why does South America and Africa look like they fit together?

South America and Africa look like they can be joined together, because once they were. About 250 million years ago Africa and South America were joined together in the continent of Pangea. There is evidence of this, because the same plants and animals fossils are found there, as well as rocks of the same age, and a glacier that covered parts of Africa, South America, India, and Australia.

Why Pangea Drifted Apart

These maps show the direction of the way that Pangea's plate tectonics moved.

Pangea separated due to Tectonic plates moving toward each other, sliding past each other, or moving away from each other. The plate tectonics formed earthquakes and volcanoes, which also caused the Supercontinent to drift apart.

How Pangea Changed.

This is a picture of what Pangea looked like, and how it changed over time.

• The first picture shows what the world looked like 250 million years ago, when it only had one continent named Pangea. Pangea was one huge continent in which all the countries were united together to form it.
• The second picture shows Laurasia, and Gondwanaland. This took place about 200 million years ago. These two Continents were formed, because Pangea started to separate due to the movement of plate tectonics. Gondwanaland included South America, Africa, India, Australia, and Antarctica. And Laurasia included North America, and Eurasia.
  
• The third picture takes place about 135 million years ago, plate tectonics moved even more, and separated the countries a lot more.
• The fourth picture is what the world looked like about 45 million years ago, where countries were so far apart, that most of them weren't connected to each other anymore.
• The last picture is a picture of the world today. Today, the world is made of seven different continents: North America, South America, Asia, Antarctica, Europe, Africa, and Australia.
  

Proof that Pangea existed

Some proof that Pangea, the Supercontinent, did exist is that scientists found fossils of the same animals and plants in South America, Africa, Antarctica, India and Australia. If the continents hadn't been joined together at some point then we wouldn't find fossils of the same species in continents that are so far away from each other because the animals wouldn't be able to get across the other side of the world. Also, the same types of rocks were found in South America and Africa. These rocks were found to have formed around the same time period.

• Question: Did Pangea exist?
• Hypothesis: Yes, Pangea did exist.
