What is Pangaea?

Back

Pangaea is the name of the giant supercontinent that existed during the late Paleozoic and early Mesozoic eras, proposed by Alfred Wegener.

How did Alfred Wegener support his theory of continental drift?

Back

Wegener supported his theory by observing the shapes of the continents and how they seemed to fit together like pieces of a jigsaw puzzle.

Front

What are symmetrical magnetic stripes in the ocean floor evidence of?

Back

They provide evidence for the spreading of ocean floor on both sides of oceanic ridges, supporting the theory of plate tectonics.

Front

What scientific theory was developed from the evidence of continental drift?

Back

The Theory of Plate Tectonics.

Front

What types of evidence support the theory of continental drift?

Back

Fossil records across continents, matching geological formations, and paleomagnetic evidence.

Front

What is the Theory of Plate Tectonics?

Back

The Theory of Plate Tectonics explains the movement of the Earth's lithosphere, which is divided into tectonic plates that float on the semi-fluid asthenosphere.

Front

What is continental drift?

Back

Continental drift is the gradual movement of continents across the Earth's surface through geological time.

Front

Who was Alfred Wegener?

Back

Alfred Wegener was a German meteorologist and geophysicist who proposed the theory of continental drift in the early 20th century.

Front

What is the significance of mid-ocean ridges?

Back

Mid-ocean ridges are underwater mountain ranges where new oceanic crust is formed through volcanic activity, playing a key role in plate tectonics.

Front

What is subduction?

Back

Subduction is the process by which one tectonic plate moves under another plate and sinks into the mantle.
