The Plate Tectonics
You should probably know that the surface of Earth is made of plates, but it is more difficult to explain what happen inside Earth. Scientists have noticed that the tectonic plates of Earth have only two sizes: there are large and small plates. One should ask: Why don't Earth have a full range of plate sizes?
To answer that question, we need to know what happen inside the Earth. But it is easier to say than realize, thus, scientists created a virtual model of a planete similar to Earth. After running this model during bilions of virtual years, they noticed that the virtual planet had the two same size of plates as Earth. They run it back to the moment these plates were created and noticed that the small plates took birth where large plates sink into the Earth. They explained this by the fact that a large plate can't sink in one piece, so it split into smaller pieces be able to sink.

The Plate Tectonics
You should probably know that the surface of Earth is made of plates, but it is more difficult to explain what happens inside Earth. Scientists have noticed that the tectonic plates of Earth only have two sizes: there are large and small plates[After a colon ':' you can just list what you're describing]. One should ask: Why doesn't Earth have a full range of plate sizes?To answer that question, we need to know what happens inside the Earth. But this is easier said than done. Thus, scientists created a virtual model of a planet similar to Earth. After running this model during bilions of virtual years, they noticed that the virtual planet had the same two plate sizes as Earth. They ran it back to the moment these plates were created and noticed that the small plates formed where large plates sank into the Earth. They explained this by the fact that a large plate can't sink in one piece, so it splits into smaller pieces in order to be able to sink.

The Plate Tectonics
You should probably know that the surface of Earth is made up of plates, but it is more difficult to explain what happens inside the Earth. Scientists have noticed that Earth's tectonic plates consist of only two sizes: there are large and small plates. One should ask: Why doesn't the Earth have a full range of plate sizes?To answer that question, we need to know what happens inside the Earth, but this is easier said than done. Thus, scientists created a virtual model of a planet similar to Earth. After running this model for billions of virtual years, they noticed that the virtual planet had the same two sizes of plates as Earth. They ran it back to the moment these plates were created and noticed that the small plates were created at the point where the large plates sank into the Earth. Their explanation for this was that a large plate can't sink in one piece, so it has to split into smaller pieces to be able to sink.
