1 - Geography is the study of the evolving character and organization of the earth’s surface by natural and human factors/processes. - Evolving implies that the discipline is dynamic in that there are processes, which bring about changes. - Character is the sum of characteristics to define an entity. - Geography is the study of the transformation of the earth’s surface by natural and human processes. It is concerned primarily with the surface of the earth. Related disciplines such as geology are concerned with the sub- surface characteristics to the extent that those characteristics influence the surface. The focus in studying this transformation is the spatial arrangement of these characteristics, or how these characteristics manifest in space. It approaches the subject matters in a variety of ways. Two extremes occur in geography’s approach: 1. The geographer may concentrate on individual places or locations on the surface of the earth and assemble the characteristics and sum them into a defining character of a place. The uniqueness of this place is emphasized . This is called regional geography - the study of the identity or the unique characteristics of the surface of the earth. 2. The geographer may look at a particular characteristic and study it on a global or universal level. He does this in order to establish the principles or theories behind these characteristics. This is systematic geography . - Regional or systematic geography depends on the manner of approach Two subdivisions of geography: Regional involves the vertical integration of characteristics. Systematic involves horizontal integration of facts. Vertical = specific peculiarities of a place Horizontal = laws/principles at a global level Because they are on different axes, people think they are orthogonal. BUT they are very much RELATED! Systematic geography Subdivisions 1. Physical geography (natural processes/phenomenon) - Physical Systematic Geography can look at the earth being made up of 4 spheres: a) atmosphere (climatology) b) hydrosphere (hydrology) c) lithosphere (geomorphology [look up meaning] and pedology [soils and how they are formed] d) biosphere (biogeography) - each of these spheres includes a subdivision of systematic geography 2. Human geography (cultural phenomenon) Physical Geography questions 1. Are human activities significantly altering the climate locally and globally? 2. Are greenhouse gasses (CO2, CH4, CFC’s) significantly altering temperature regimes where they are produced? Physical geography applies to the environment through biodiversity. Biodiversity has become an important focus because 1. It offers a variety of bioactive compounds, which are useful to humanity in combating pests and diseases and improving crop yields. 2.
