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] Listed roughly from outermost to innermost the named spheres of the Earth are:
In Mesopotamian cosmology, four rivers flowing out of the garden of creation, which is the center of the world, define the four corners of the world. [1] From the point of view of the Akkadians, the northern geographical horizon was marked by Subartu, the west by Mar.tu, the east by Elam and the south by Sumer; later rulers of all of Mesopotamia, such as Cyrus, claimed among their titles LUGAL ...
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 ...
Earth's location in the Universe. Universe – all of time and space and its contents. Observable universe – spherical region of the Universe comprising all matter that may be observed from Earth at the present time, because light and other signals from these objects have had time to reach Earth since the beginning of the cosmological expansion.
The transition between the inner core and outer core is located approximately 5,150 km (3,200 mi) beneath Earth's surface. Earth's inner core is the innermost geologic layer of the planet Earth. It is primarily a solid ball with a radius of about 1,220 km (760 mi), which is about 19% of Earth's radius [0.7% of volume] or 70% of the Moon's radius.
They were believed to explain the motions of the four terrestrial elements: Earth, Water, Air, and Fire. In modern texts and in Earth system science , geosphere refers to the solid parts of the Earth ; it is used along with atmosphere , hydrosphere , and biosphere to describe the systems of the Earth (the interaction of these systems with the ...
The tectonic plates of the lithosphere on Earth Earth cutaway from center to surface, the lithosphere comprising the crust and lithospheric mantle (detail not to scale). A lithosphere (from Ancient Greek λίθος (líthos) 'rocky' and σφαίρα (sphaíra) 'sphere') is the rigid, [1] outermost rocky shell of a terrestrial planet or natural satellite.
Carries six instruments to observe interactions among the four spheres for Earth's systems: oceans, land, atmosphere, and biosphere. [5] ASNARO-2: Active JAXA: 2018 Aura: Active NASA 2004 Studies earth's ozone, air quality, and climate though observation of composition, chemistry, and dynamics of the atmosphere. [6] Badr-B: Active
