Continental Drift and Pangaea

In 1911, meteorologist Alfred Wegener discovered identical plant and animal fossils on opposite sides of the Atlantic Ocean, leading him to propose the theory of continental drift. He observed that the coastlines of South America and Africa fit together and found similar species in East Africa and Madagascar. Wegener theorized that all continents were once part of a supercontinent called Pangaea, which later split apart. Despite initial skepticism due to the lack of a mechanism for continental movement, Wegener's theory laid the groundwork for modern geology.

What sparked Alfred Wegener's curiosity about the distribution of species across continents?

• The study of ocean currents

• The analysis of mountain ranges

• The observation of similar climates in different regions

• The discovery of identical fossils on different continents

What did Wegener notice about the coastlines of South America and Africa?

• They had similar climates

• They had the same types of forests

• They had matching coastlines

• They were both rich in minerals

Which two regions did Wegener find had similar species of land mammals?

• North America and Europe

• East Africa and Madagascar

• India and Antarctica

• Australia and Asia

What name did Wegener give to the supercontinent he proposed?

• Atlantis

• Gondwana

• Pangaea

• Laurasia

What did Wegener suggest happened to Pangaea over millions of years?

• It merged with another supercontinent

• It sank into the ocean

• It split into smaller continents

• It remained intact

What was the main reason Wegener's theory was initially rejected by his peers?

• Contradictory fossil records

• Inaccurate climate data

• Lack of evidence

• No mechanism for continental movement

What did Wegener call his theory about the movement of continents?

• Seafloor Spreading

• Continental Drift

• Plate Tectonics

• Tectonic Shift

How did Wegener contribute to the understanding of Earth's geological history?

• By discovering new minerals

• By proposing the theory of continental drift

• By mapping ocean currents

• By studying volcanic activity

What was the long-term impact of Wegener's theory?

• It laid the foundation for plate tectonics

• It was completely disproven

• It was accepted immediately

• It led to the discovery of new continents
