Earth as an evolving planetary system / Земля как эволюционирующая планетная система
A system is an entity composed of diverse but interrelated parts that function as a whole (Kump et al., 1999a). The individual parts, often called components, interact with each other as the system evolves with time. Components include reservoirs of matter or energy, described by mass or volume, and subsystems, which behave as systems within a system. In recent years, the Earth has been considered a complex planetary system that evolved over 4.6 billion years of time. It includes reservoirs, such as the crust, mantle, and core, and subsystems, such as the atmosphere, hydrosphere, and biosphere. Because many of the reservoirs in the Earth interact with each other and with subsystems, such as the atmosphere, there is an increasing tendency to consider most or all of the Earth’s reservoirs as subsystems. <...>
