Many of the subsystems are characterized as "spheres", coinciding with the shape of the planet. The four spheres (for which most of the other spheres are a subtype of) are the atmosphere, the biosphere, the hydrosphere and the geosphere. Earth's ecosphere lies it self within the heliosphere (the Sun's astrosphere). [4]
In Earth science, it is common to conceptualize the Earth's surface as consisting of several distinct layers, often referred to as spheres: the lithosphere, the hydrosphere, the atmosphere, and the biosphere, this concept of spheres is a useful tool for understanding the Earth's surface and its various processes [30] these correspond to rocks ...
Antarctica, the continent surrounding the Earth's South Pole, is the coldest place on earth and is almost entirely covered by ice. Antarctica was discovered in late January 1820 . Too cold and dry to support virtually any vascular plants, Antarctica's flora presently consists of around 250 lichens , 100 mosses , 25-30 liverworts , and around ...
The Earth's radius is the distance from Earth's center to its surface, about 6,371 km (3,959 mi). While "radius" normally is a characteristic of perfect spheres, the Earth deviates from spherical by only a third of a percent, sufficiently close to treat it as a sphere in many contexts and justifying the term "the radius of the Earth".
Wyld's Great Globe, located in London's Leicester Square from 1851-1862, was a hollow globe 60 feet 4 inches (18.39 m) in diameter designed by mapmaker James Wyld. Visitors could climb stairs to view a plaster of Paris model of the Earth's surface, complete with mountains and rivers to scale.
Carries six instruments to observe interactions among the four spheres for Earth's systems: oceans, land, atmosphere, and biosphere.

Your birth chart's 3rd House thrives on this dynamic interplay, echoing the ongoing dialogue between us and our immediate world. Any drop of wisdom, trendy catchphrase, or backward wisdom falls ...
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.
