Biosphere, relatively thin life-supporting stratum of Earth’s surface, extending from a few kilometers into the atmosphere to the ocean’s deep-sea vents. This global ecosystem continuously cycles matter. It is composed of organisms (biota) and the abio

such as chemically forced global climate change. The work is aimed at those students interested in the emerging scientific discipline. Earth Systems Science is an integrated discipline that has been rapidly developing over the last two decades. New information is included in this updated edition so ...
(Physical Geography) the circulation of the earth's water, in which water evaporates from the sea into the atmosphere, where it condenses and falls as rain or snow, returning to the sea by rivers or returning to the atmosphere by evapotranspiration. Also called:hydrologic cycle ...
(see Figure 1) moves along another circle, called the deferent, with its center at the earth. Because a deferent with one epicycle could not explain many irregularities in the motions of the planets, systems of epicycles were introduced. It was believed that the center of the second epi...

Such systems are dynamic systems, which means that they involve the transport of masses over distances and in definite time intervals. Cycles generated by such systems can be used as time units. A special example is the earth solar system which can generate cycles from daily periods to orbital...

It can be argued that this was partly a consequence of the complex nature of fracture in crust and in part because evidence of brittle phenomena in the natural laboratory of the earth is often obliterated or obscured by other geological processes. While it is well understood that the spatial ...
