Test Theory of Continental Drift

Front

What is the Theory of Continental Drift?

Back

The Theory of Continental Drift is the idea that continents have moved over geological time and were once joined together in a single landmass called Pangaea.

Front

Who proposed the Theory of Continental Drift?

Back

Alfred Wegener proposed the Theory of Continental Drift in the early 20th century.

Front

What evidence did Wegener use to support his theory?

Back

Wegener used evidence from fossils, rock types, and the fit of coastlines to support his theory.

Front

Why was Wegener's theory initially rejected?

Back

Wegener's theory was initially rejected because he could not provide a convincing explanation for how the continents moved.

Front

What are the three main types of evidence supporting the Theory of Continental Drift?

Back

The three main types of evidence are fossils, landforms, and climate.

Front

What is the significance of matching fossils found on different continents?

Back

Matching fossils found on different continents suggest that those continents were once connected.

Front

How do the Appalachian Mountains and the Scottish Highlands provide evidence for continental drift?

Back

The similarities in the rock types and geological features of the Appalachian Mountains and the Scottish Highlands suggest they were once part of the same mountain range.

Front

What role do glacial deposits play in supporting the Theory of Continental Drift?

Back

Glacial deposits found in now-tropical regions indicate that those continents were once located near the poles.

Front

What is Pangaea?

Back

Pangaea is the name given to the supercontinent that existed during the late Paleozoic and early Mesozoic eras, before breaking apart into the continents we know today.

Front

What is the concept of 'fit' in the context of continental drift?

Back

The concept of 'fit' refers to how the coastlines of continents, such as South America and Africa, appear to fit together like pieces of a puzzle.
