Globes
Since Antiquity it has been known that Planet Earth is round. This was recognized, for example, by Aristotle. Only in the 18th century, with better technological resources, the main landmasses and the real shape of the continents were known.
Earth is the third planet from the Sun and the fifth largest planet in the solar system in terms of size and mass. The Blue Planet has an amazing variety of natural wonders, home to humans and many other animals.
Maps of Continents
The surface of the Earth is approximately 71% water and 29% land. The former portion constitutes the World Ocean, the single largest feature of the planet and one that connects all places on the globe. The World Ocean is divided by the intervening continental landmasses into five major ocean basins, which are (in decreasing order of size) the Pacific, Atlantic, Indian, Southern, and Arctic.
About 97.5% of the Earth's water is saltwater. Of the 2.5% that is fresh, about two-thirds is frozen, mostly locked up in the Antarctic ice sheets and mountain glaciers worldwide. If all the surface ice on earth fully melted, the sea level would rise about 70 m.
Icebergs in Antarctica. The continent was first explored in the 18th century, according to historic records.
