1. Magellan's expedition, which began in 1519, was the first to successfully circumnavigate the globe, proving the Earth was round.
2. During the voyage, Magellan's crew made important observations about the size and scale of the solar system, contributing to the acceptance of the heliocentric model.
3. The expedition provided the first detailed mapping of major ocean routes, including the Strait of Magellan, which connects the Atlantic and Pacific Oceans.
4. Magellan's voyage demonstrated the feasibility of long-distance sea travel and paved the way for future exploration and colonization efforts.
5. The successful circumnavigation of the globe by Magellan's crew had a profound impact on the understanding of the Earth's size, shape, and place within the solar system.

Review Questions

• Explain how Magellan's voyage contributed to the acceptance of the heliocentric model of the solar system.
  • Magellan's expedition provided crucial evidence in support of the heliocentric model, where the planets, including Earth, orbit around the Sun at the center of the solar system. During the voyage, the crew made observations about the size and scale of the solar system that contradicted the prevailing geocentric model, which placed Earth at the center. The successful circumnavigation of the globe also demonstrated the Earth's curvature, further reinforcing the concept of a spherical planet orbiting the Sun.
• Describe the significance of the Strait of Magellan in the context of the expedition's accomplishments.
  • The Strait of Magellan, discovered and navigated by Magellan's crew, was a crucial component of the first successful circumnavigation of the globe. This narrow waterway, connecting the Atlantic and Pacific Oceans, allowed the expedition to cross between the two major bodies of water, enabling them to complete their journey around the world. The mapping and exploration of the Strait of Magellan not only demonstrated the feasibility of long-distance sea travel but also provided valuable information about the geography and oceanography of the region, which would inform future expeditions and maritime activities.
• Evaluate the broader impact of Magellan's expedition on the understanding of the Earth's size, shape, and place within the solar system.
  • Magellan's successful circumnavigation of the globe had a profound and lasting impact on the understanding of the Earth's size, shape, and place within the solar system. By proving the Earth was round and providing the first detailed mapping of major ocean routes, the expedition challenged the prevailing geocentric model and paved the way for the acceptance of the heliocentric model. The expedition's observations about the scale and vastness of the solar system also contributed to a more accurate understanding of the Earth's position and role within the larger planetary system. Additionally, the successful circumnavigation demonstrated the feasibility of long-distance sea travel, which would facilitate future exploration, colonization, and the exchange of ideas and resources on a global scale.
