“Were South America and Africa once joined and then moved into their current positions?” This question was asked by….. Wegener found that animals and plants found in East Africa are also found in other lands. Therefore, he reached the conclusion that these continents were joined earlier.

What caused South America and Africa to spread apart?

About 135 million years ago Laurasia was still moving, and as it moved it broke up into the continents of North America, Europe and Asia (Eurasian plate).

Why was Pangaea not accepted?

Despite having this geological and paleontological evidence, Wegener’s theory of continental drift was not accepted by the scientific community, because his explanation of the driving forces behind continental movement (which he said stemmed from the pulling force that created Earth’s equatorial bulge or the …

Why did no one believe Wegener’s theory?

The main reason that Wegener’s hypothesis was not accepted was because he suggested no mechanism for moving the continents. He thought the force of Earth’s spin was sufficient to cause continents to move, but geologists knew that rocks are too strong for this to be true.

How South America and Africa fit together?

South America and Africa were once together, but were split apart by the formation of a diverging plate boundary. This is confirmed by matches between the rocks and fossils of the two continents. Plate motion, not continents drifting, explains this. The two continents are still moving away from each other today.

How big was the tsunami that killed the dinosaurs?

Now, scientist say they have found evidence of the resulting giant tsunami that swamped much of the Earth. In a study published in the journal Earth & Planetary Science Letters, researchers report how they discovered 52-foot-tall “megaripples” nearly a mile below the surface of what is now central Louisiana.

How does South America and Africa fit together?

If you have a large world map in your room, go over the different continents with your students and have them try to fit other continents and areas together. If you rotate North America toward the right it fits against Europe. The south coast of Australia fits against Antarctica. India fits between Africa and Australia.

When did Gondwana separate from South America and Africa?
