Planet Earth is made up of four overlapping subsystems that contain all of world’s land masses, water sources, living organisms, and gases. These four subsystems are known as spheres. Geographers break down the Earth’s systems into four spheres that make up the world’s air (atmosphere),...

Applying the three-fold Reynolds averages to the governing equations with Boussinesq approximation, with the averages defined on the former three sub-systems, we derive the governing equation sets of the four sub-systems and refer to their sum as “the ocean dynamic system”. In these equation...
sub-systems,we derive the governing equation sets of the four sub-systems and refer to their sum as "the ocean dynamic system".In these equation sets,the interactions among different motions appear in two forms:the first one includes advection transport and shear instability generation of larger ...
Countries globally trade with tons of waste materials every year, some of which are highly hazardous. This trade admits a network representation of the world-wide waste web, with countries as vertices and flows as directed weighted edges. Here we investi
4), for which we compared the placement distributions for each subhabitat. Interestingly, most placements occurred close to the tips of the reference tree, indicating that our long-read dataset adequately represents the diversity recovered by short-read metabarcoding (Extended Data Fig. 4). Further...
The anthroposphere has evolved into a vital component of the Earth’s ecosystem, heavily influencing and influenced by the other four Earth systems [25]. Figure 1 shows each sphere’s interconnection with its concepts. Figure 1. Five spheres of the Earth system. 3. Methodology A systematic ...
In reality, human beings have already become an indispensable part of the Earth’s ES system. Supporting the sustainable development of the economy and society is an important reason to study ES [43]. Therefore, the present study evaluates the state of ES in border areas from five subsystems...
