A long long time ago, maybe about 1,000,000 years ago, the mantel which is under the earth's crust (and we're standing on the earth's crust) was just like the earth's crust. But now it is hot melted rock. Over the years the mantel gets hotter. The Mantel gets so hot that it melts through the continents and separates them even more. Answer Plate Tectonics. The earths crust is floating on the molten magma which is what the centre of the Earth is made of. There are currents in the magma which tore the original single land mass (Pangea) apart and dragged the pieces apart. The pieces, called plates, are still drifting. Sometimes they crash into each other like India and Asia.

Pangaea broke up into what two continents?
Pangaea broke into Gondwanaland and Laurasia.
Why might continents with an ocean between them have sinilarities?
Because the continents were once one large piece of land. As one large piece of land, there were no continents. Sections broke away over time, likely aided by the fact that the ocean floor is constantly expanding each year. Look up Pangea and see image in Related Links.
What do you call the crust making up the continents?
The crust that makes up the continents, or land masses on Earth is called continental crust. The crust that makes up the oceans is called oceanic crust.
Are the continents of Africa and Asia smaller or larger than the rest of the continents combined?
Together, the continents of Asia and Africa make up about 75,000,000 sq km. The rest of the continents together make up just under that amount. So really, they would be neither "very much" larger or smaller, but almost the same.
Is silica the bedrock that makes up the bulk of the continents?
No. Silica is a compound found in many rocks. The rock that makes up the bulk of the continents is granite, which does contain quartz which is a form of silica.
Which fossil occurs on the landmasses what does this suggest about when these particular continents broke up?
This isn't the full answer sorry but The globetrotters plant
What fossils occur on the most landmasses when does this suggest about when these particular continents broke up?
This isn't the full answer sorry but The globetrotters plant
What does this suggest about when these particular continets broke up?
This suggests that these continents broke up around 200 million years ago during the Mesozoic era. This breakup eventually led to the formation of the Atlantic Ocean.
What does glossoptetsis suggest about when these particular continents broke up?
Glossopteris was a plant whose fossils have been found across South America, Africa, India, Antarctica, and Australia, suggesting that these continents were once connected as part of the supercontinent Gondwana. This supports the idea that these continents broke up around 180 million years ago during the Jurassic Period.

What was the name of the continent that then broke up into 7 continents?
Pangea
What were the two continents called when Pangaea broke into two?
The two continents that formed when Pangaea broke apart are Laurasia in the north and Gondwana in the south. These two supercontinents eventually broke up further to form the continents we have today.
What was the name of the supercontinent before all of the continents broke up?
Pangea.
What did wegner think happened to this supercontinent?
Wegner thought that the continents broke up.
Pangaea broke up into what two continents?
Pangaea broke into Gondwanaland and Laurasia.
What is the name of the continents before they broke up?
Before the continents broke apart, they were part of a single supercontinent called Pangaea. It is believed that Pangaea existed around 300 million years ago during the Paleozoic and Mesozoic eras.
