What Causes Subarctic and Polar Climates? two much larger fields of study - Geography and Earth Sciences. The components of atomic structure can be described as an atomic system.

Herodotus wrote a number of volumes that described the human and physical geography of the various regions of the PERSIAN EMPIRE. The main stimulus for the field since its founding has been that of evolution, plate tectonics and the theory of island biogeography. Evidence for this idea came from observations of lunar eclipses. The subject of this speech was that human activity was having a destructive impact on land, especially through deforestation and land conversion.

It involves an understanding of coastal weathering processes, particularly wave action, sediment movement and weathering, and also the ways in which humans interact with the coast. A good example of a system within systems is the hierarchy of systems found in the universe.

It covers a wide range of topics, including marine organisms and ecosystem dynamics (biological oceanography); ocean currents, waves, and geophysical fluid dynamics (physical oceanography); plate tectonics and the geology of the sea floor (geological oceanography); and fluxes of various chemical substances and physical properties within the ocean and across its boundaries (chemical oceanography). Phenomena or elements studied in physical geography include rocks and minerals, landforms, soils, animals, plants, water, atmosphere, rivers and other water bodies, environment, climate and weather, and oceans.
