Continental Drift

Front

What is Continental Drift?

Back

The theory that continents have moved over geological time and were once joined together in a supercontinent called Pangaea.

Front

What is Pangaea?

Back

A supercontinent that existed during the late Paleozoic and early Mesozoic eras, where all continents were once connected.

Front

What evidence did Alfred Wegener use to support his theory of Continental Drift?

Back

Evidence from landforms, fossils, climate, and glacier scars.

Front

What is the significance of glacier scars in relation to Continental Drift?

Back

They indicate that continents like Africa were once located in colder climates, supporting the idea of continental movement.

Front

What type of evidence was NOT used by Alfred Wegener?

Back

Evidence from human remains.

Front

How do fossils support the theory of Continental Drift?

Back

Fossils of the same species found on different continents suggest that these continents were once connected.

Front

What is plate tectonics?

Back

The scientific theory that describes the large-scale movements of Earth's lithosphere, which includes the movement of continents.

Front

What role do mountain ranges play in the theory of Continental Drift?

Back

Mountain ranges that line up across continents suggest that those continents were once joined.

Front

What is the relationship between Continental Drift and climate evidence?

Back

Climate evidence, such as glacier scars, shows that continents have moved to different climate zones over time.

Front

What is the concept of sea floor spreading?

Back

The process by which new oceanic crust is created at mid-ocean ridges and older crust is pushed away, supporting the movement of continents.
