Document Summary
Geography is the science that studies the relationships among natural systems, geographic areas, society, cultural activities, and the interdependence of all these over space. Spatial: nature and character of physical space, its measurement, and distribution of things within it: five important spatial themes: location, region, human-earth relationships, movement and place. Process: set of actions or mechanisms that operate in some special order, governed by physical, chemical and biological laws. Therefore, physical geography is the spatial analysis of all the physical elements and processes that make up the environment. Five themes of geographic science (lmrhp): location- absolute and relative location of earth; location answers the question where, movement- communication, movement, circulation, migration and diffusion across. Negative feedback: feedback info discourages response in the system- such as dieting. Steady-state equilibrium: where rates of inputs and outputs, amounts of energy and matter are equal. Dynamic equilibrium: changing trends of increasing/decreasing system operations. Threshold: abrupt changes in functional operation i. e. sudden landslide.
