6 de enero: ¿Por qué se mueven los continentes?

The video discusses the theory of continental drift proposed by Benner, highlighting the evidence he presented, such as fossils found across continents, and the initial lack of a mechanism to explain it. It traces the historical context of the idea, noting early suspicions about the fit of Africa and South America's coastlines. The video then transitions to the modern understanding of plate tectonics, which explains the movement of Earth's lithosphere and the formation of geological features. It concludes with a reflection on the ever-changing nature of Earth's surface and the philosophical implications of change.

What was the main reason Benner's theory of continental drift initially lacked support?

• He did not provide any evidence.

• He could not explain the mechanism of movement.

• His theory was too complex to understand.

• He proposed the theory too late.

Which continents' coasts were suspected to fit together as early as 1596?

• North America and Europe

• Asia and Australia

• Antarctica and Asia

• Africa and South America

What theory has replaced continental drift in explaining the movement of the Earth's surface?

• Plate Tectonics

• Seafloor Spreading

• Mountain Formation

• Volcanic Activity

According to plate tectonics, what is the outermost layer of the Earth divided into?

• Tectonic Plates

• Continental Shelves

• Oceanic Ridges

• Volcanic Arcs

What geological phenomena occur at the boundaries of tectonic plates?

• Formation of deserts

• Erosion of mountains

• Earthquakes and volcanic activity

• Creation of rivers
