Back

Pangea was a supercontinent that existed during the late Paleozoic and early Mesozoic eras, where all the continents were joined together.

Front

What does the continental drift hypothesis propose?

Back

The continental drift hypothesis suggests that continents have moved over geological time and were once connected.

Front

What evidence supports the idea of continental drift?

Back

Similar fossils found on different continents, matching geological formations, and the fit of continental coastlines.

Front

Who proposed the theory of continental drift?

Back

Alfred Wegener proposed the theory of continental drift in the early 20th century.

Front

What are tectonic plates?

Back

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

Front

What is the significance of similar fossils in South America and Africa?

Back

They suggest that these continents were once connected, supporting the theory of continental drift.

Front

How do the Appalachian Mountains relate to continental drift?

Back

The Appalachian Mountains match similar mountain ranges in Europe, indicating that North America and Europe were once connected.

Front

What is a supercontinent?

Back

A supercontinent is a large landmass that contains all or most of the Earth's continents.

Front

What role do convection currents play in plate tectonics?

Back

Convection currents in the Earth's mantle drive the movement of tectonic plates.

Front

What is the difference between a hypothesis and a theory?

Back

A hypothesis is an educated guess that needs testing, while a theory is a well-supported explanation based on evidence.
