The three ways that geography was effected by this voyages were:
- they finally proved that the Earth is round;
- the discovery of new continents and islands;
- mapping;
The voyages of this period of time were very important for the geography as a science, but also for the whole human kind. With them, it was finally proved that our planet is round, and thus that question and debates were given the answer that everyone was looking for for so long. Four new continents, and thousands of islands were discovered, and that gave a whole new perspective of the world, its shape, land masses, and water bodies. Since lots of new discoveries were made, and there was an ever-growing number of places discovered, the mapping was crucial, and there was a lot of focus on it which contributed to new techniques of mapping.
