Northern Hemisphere. Northern Hemisphere shaded blue. The hemispheres appear unequal here because Antarctica is not shown. Northern Hemisphere from above the North Pole. The Northern Hemisphere is the half of Earth that is north of the Equator. For other planets in the Solar System, north is defined as being in the same celestial hemisphere ...
This hemisphere contains approximately 68% of Earth's landmass and is home to about 90% of the global population. [4] It includes North America, Europe, Asia, and most of Africa. Southern Hemisphere: The half that lies south of the Equator. It contains approximately 32% of Earth's landmass and is home to about 10% of the global population.
In terms of shape, Europe is a collection of connected peninsulas and nearby islands. The two largest peninsulas are Europe itself and Scandinavia to the north, divided from each other by the Baltic Sea. Three smaller peninsulas— Iberia, Italy, and the Balkans —emerge from the southern margin of the mainland.
Map all coordinates using OpenStreetMap. The 45th parallel north is a circle of latitude that is 45 degrees north of Earth's equator. It crosses Europe, Asia, the Pacific Ocean, North America, and the Atlantic Ocean. The 45th parallel north is often called the halfway point between the equator and the North Pole, but the true halfway point is ...

The remaining boundaries concern the association of islands and archipelagos with specific continents, notably: the delineation between Africa, Asia, and Europe in the Mediterranean Sea; the delineation between Asia and Europe in the Arctic Ocean; the delineation between Europe and North America in the North Atlantic Ocean;
In geology, a continent is defined by continental crust, which is a platform of metamorphic and igneous rock, largely of granitic composition. Continental crust is less dense and much thicker than oceanic crust, which causes it to "float" higher than oceanic crust on the dense underlying mantle.
The Pleistocene ( / ˈplaɪstəˌsiːn, - stoʊ -/ PLY-stə-seen, -stoh-; [5] [6] often referred to colloquially as the Ice Age) is the geological epoch that lasted from c.2.58 million to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union ...
