What is Pangea?

Back

Pangea was a supercontinent that existed during the late Paleozoic and early Mesozoic eras, approximately 335 to 175 million years ago, when all the continents were joined together.

What evidence did Alfred Wegener use to support his theory of continental drift?

Back

Wegener used evidence such as the shape of the continents, similar fossils found on separate continents, and tree fossils found in odd places.

What is a convergent boundary?

Back

A convergent boundary is a tectonic plate boundary where two plates move toward each other, often causing earthquakes, volcanic activity, and the formation of mountains.

What is a divergent boundary?

Back

A divergent boundary is a tectonic plate boundary where two plates move away from each other, leading to the formation of new crust, such as mid-ocean ridges.

What is a transform boundary?

Back

A transform boundary is a tectonic plate boundary where two plates slide past each other horizontally, causing earthquakes.

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact with each other, causing geological activity.

Why was Wegener's theory initially rejected?

Back

Wegener's theory was initially rejected because he could not explain how the continents moved.

What is the significance of fossils in understanding Pangea?

Back

Fossils of similar species found on different continents provide evidence that these continents were once connected.
