¿Cómo se formaron los continentes?

The video discusses the concept of Pangaea, a supercontinent that existed when most of the world's landmass was united. Alfred Wegener, a German meteorologist, proposed the theory of continental drift in 1912, suggesting that continents slowly separate over time. Initially, his theory was not widely accepted due to a lack of a convincing mechanism, but he provided evidence such as the puzzle-like fit of South America and Africa and similar fossils found on both coasts. Later scientific discoveries confirmed that continents move continuously as part of tectonic plates. These plates, which formed over 4 billion years ago, are in constant motion. The video also speculates on how the continents might look in 250 million years.

Who was the first to propose the idea of a supercontinent and what was the theory called?

• Charles Darwin, Evolution

• Isaac Newton, Gravity

• Albert Einstein, Relativity

• Alfred Wegener, Continental Drift

What evidence did Wegener use to support his theory of continental drift?

• The speed of continental movement

• The discovery of tectonic plates

• The formation of new rocks

• The presence of similar fossils on different continents

What are tectonic plates?

• Areas with frequent earthquakes

• Regions of high volcanic activity

• Layers of the Earth's atmosphere

• Large blocks of rock that make up the Earth's crust

How long ago did the Earth's crust solidify, forming tectonic plates?

• 10,000 years ago

• Over 4 billion years ago

• 500 million years ago

• 1 million years ago

How will the Earth's surface change in 250 million years?

• The continents will disappear completely

• The continents will have a very different appearance

• The continents will remain in the same position

• The continents will merge into a single landmass
