    It's possible for the hydrosphere to be highly distributed throughout other component spheres such as the geosphere and atmosphere. There are about 1.4 billion km of water on Earth. That includes liquid water in the ocean, lakes, and rivers. It includes frozen water in snow, ice, and glaciers, and water that's underground in soils and rocks.

    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 climate system is a complex system with five interacting components: the atmosphere (air), the hydrosphere (water), the cryosphere (ice and permafrost), the lithosphere (earth's upper rocky layer) and the biosphere (living things). [28]: 1451 Climate is the statistical characterization of the climate system.

    Earth systems and examples of Earth system interactions across mountain belts. Earth system interactions across mountain belts are interactions between processes occurring in the different systems or "spheres" of the Earth, as these influence and respond to each other through time.

    The five components of the climate system all interact. They are the atmosphere, the hydrosphere, the cryosphere, the lithosphere and the biosphere. [1]: 1451 Earth's climate system is a complex system with five interacting components: the atmosphere (air), the hydrosphere (water), the cryosphere (ice and permafrost), the lithosphere (earth's upper rocky layer) and the biosphere (living things).

  8. Spheres of exchange - Wikipedia

    Spheres of exchange is a heuristic tool for analyzing trading restrictions within societies that are communally governed and where resources are communally available. [1] Goods and services of specific types are relegated to distinct value categories, and moral sanctions are invoked to prevent exchange between spheres.

    The Sinews of Old England (1857) by George Elgar Hicks shows a couple "on the threshold" between female and male spheres. [1]Terms such as separate spheres and domestic–public dichotomy refer to a social phenomenon within modern societies that feature, to some degree, an empirical separation between a domestic or private sphere and a public or social sphere.
