  2. Hemispheres of Earth - Wikipedia

    en.wikipedia.org/wiki/Hemispheres_of_Earth

    Northern Hemisphere: The half that lies north of the Equator. 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 ...

  3. Northern Hemisphere - Wikipedia

    en.wikipedia.org/wiki/Northern_Hemisphere

    The glaciations that occurred during the glacial period covered many areas of the Northern Hemisphere. Northern hemisphere glaciation during the last ice ages. The setup of 3 to 4 kilometer thick ice sheets caused a sea level lowering of about 120 m. The Arctic is a region around the North Pole (90° latitude). Its climate is characterized by ...

    The differences shown on the plot are in arc minutes. In the Northern hemisphere (positive latitudes), θ ≤ χ ≤ μ ≤ ξ ≤ β ≤ ϕ; in the Southern hemisphere (negative latitudes), the inequalities are reversed, with equality at the equator and the poles. Although the graph appears symmetric about 45°, the minima of the curves ...

  6. Geographical zone - Wikipedia

    en.wikipedia.org/wiki/Geographical_zone

    The five main latitude regions of Earth's surface comprise geographical zones, [1] divided by the major circles of latitude. The differences between them relate to climate. They are as follows: The North Frigid Zone, between the North Pole at 90° N and the Arctic Circle at 66°33′50.3″ N, covers 4.12% of Earth's surface.

    With the Northern Hemisphere well into the winter months, it may seem like temperatures are cold enough already. However, a deep freeze, thanks to the polar vortex dipping down from Siberia, is ...

  8. List of circles of latitude - Wikipedia

    en.wikipedia.org/wiki/List_of_circles_of_latitude

    The equator, a circle of latitude that divides a spheroid, such as Earth, into the northern and southern hemispheres. On Earth, it is an imaginary line located at 0 degrees latitude . 0°

  9. Circle of latitude - Wikipedia

    en.wikipedia.org/wiki/Circle_of_latitude

    Lines of latitude appear horizontal with varying curvature in this projection; but are actually circular with different radii. All locations with a given latitude are collectively referred to as a circle of latitude. The equator divides the planet into a Northern Hemisphere and a Southern Hemisphere, and has a latitude of 0°.
